Consider some of the design features of the old (releases before 2014) Renault Logan car body. The aspects of its durability, comfort and passive safety.
Renault Logan - advantages and disadvantages
Despite the appearance in 2014 of a new generation of the model, the Renault Logan car in the same “clothing” will still prevail numerically for a long time. Therefore, interest in the model in the old body has not lost its relevance.
Comfort
The dimensions of the new Renault Logan are not quite common for a B-class car. With a fairly typical length of 4250 mm, its width is 1742 mm, which is more typical for class C or even C plus models. Additional 40-70 mm provide quite acceptable space in the cabin - on back seat three passengers are comfortably accommodated even in winter clothes.
As for the interior of the new car - what do you want from a cheap "budget" car? However, inexpensive plastic dashboard and synthetic fabric upholstery look quite decent.
For such a modest length of the passenger compartment, the doorways are surprisingly wide, and the door frames go to the edge of the roof. This design, coupled with low thresholds, contributes to quite sufficient ease of boarding and disembarking.
At a good level and soundproofing. decline external noise contributes to the effective anti-noise mastic, which processed the machine. The natural noise produced by it is minimized by precise fitting and quality welding of body parts.
Perhaps the only disadvantage that old car- not too spacious trunk.
Security
Competent engineering and technological solutions adopted in the design of the body provide a high level of passive safety of the new car.
In the most dangerous frontal collision, its front part is easily crushed, extinguishing, at the same time, a significant share of the impact energy. For new cars with a longer length and longitudinal engine, this is easy to achieve. For machines with a transverse arrangement power unit and short engine compartment the task becomes much more difficult. However, the engineers of the Renault concern successfully coped with this problem. Variable stiffness of the power elements of the front end provide the desired effect. In addition, this design leads to the fact that during a frontal impact, the engine and gearbox do not push into the passenger compartment, which is fraught with serious injuries to the legs of those sitting in front, but go down, partially under the floor of the passenger compartment.
In side collisions, the protection of the driver and passengers is provided by a carefully thought-out power scheme of the sidewalls and the door frame. Upon impact, the doors and pillars are not crushed exactly in his direction, but slightly down, thus removing the deformation from the most vulnerable part of the body.
The high rigidity of the vertical elements of the load-bearing frame of the body and its roof adequately protects the driver and passengers in the event of a car overturning.
Durability
The often encountered statement that the Renault Logan body is completely galvanized is fundamentally wrong. Such a solution is not often used even on cars of higher classes, since continuous galvanizing not only makes the car heavier, but also significantly increases the cost of the car. Yes, this is often completely useless, since the rate of corrosion in different parts of the body varies significantly, especially in older cars.
Until 2007, the old Renault Logan had the following parts galvanized:
- front fenders;
- rear fenders;
- bottom edge of frame windshield.
Later, the new Renault Logan added to the list of galvanized elements:
- doors;
- trunk lid;
- roof panel.
In addition to these galvanized parts, the increase in anti-corrosion protection of the new Logan is achieved by using innovative technology, the so-called "sacrificial anodes". The bottom line is that in places most prone to rusting, special inserts are installed - zinc protectors that corrode instead of mating parts, prolonging their service life for a long time. The protectors have a much higher degree of oxidation, as a result of which, as it were, they “pull” these processes onto themselves. Such new elements are installed, for example, under the door hinges, hinges of the hood and trunk lid, in a number of other places.
The durability of Logan's body parts, both galvanized and others, is also ensured by the photophoretic priming technique. This technology not only ensures the penetration of soil into the most inaccessible places (hidden interfaces, welds, internal cavities), but also initiates an electrochemical process that significantly slows down the opposite process of corrosion.
Painting at the Renault plant is fully robotized, which eliminates the "human" factor. Unpainted surface fragments or insufficient thickness of the paint layer are excluded, which also favorably affects durability.
The last stage of protection is the factory and additional pre-sale anti-corrosion treatment. For these purposes, effective mastics are used, which are also anti-noise.
maintainability
The simple forms of body parts from which Renault Logan is assembled allow for high-quality body repair even with fairly large deformations. And after the repair of minor damage, the part often does not require touch-up, since the factory paint does not peel off, but repeats the shape of the dent.
For our country, the rapid decay and erosion of car body parts is the number one problem. high humidity, constant fluctuations temperatures, the use of aggressive anti-icing reagents quickly do their job and render the metal unusable within a couple of years. Today we will talk about how Renault Logan engineers found a way out of this situation, and how a galvanized body can help the car owner.
Why is this needed?
At the moment, to protect the car from corrosion, there are a number of various ways. For the most part, all of these methods come down to just two.
The first option is to use as many polymer moldings as possible on the body, which reliably cover most of the "problem" places and completely exclude the penetration of moisture to the metal, which does not have an anti-corrosion coating. The second way is to cover the body, bottom and arches special formulations, which preserve the metal and thereby repeatedly prolong the life of the car.
By purchasing Renault Logan, you can make sure for yourself that there is no reason to worry about the bottom of the car. Indeed, even from the factory, this sedan is coated with a factory anti-corrosion coating, which is able to endure with dignity all the hardships of our climate for at least five years. Next, you should cover the bottom again and provide a few more years of guaranteed absence of corrosion.
If the bottom of the Renault Logan is securely protected, then what about the rest of the body? Car owners are well aware that over the course of operation, literally five to seven years after active car trips, the fleeting “eating” of the wings, the bottom of the doors, the hood and the trunk of the car with corrosion begins. Moreover, if you start this situation and do nothing to remove rust and preserve the metal, the rust quickly develops into through holes and leaves no chance for the machine element to recover.
A layer of zinc, which is not found on most budget cars, is applied under the paint layer. It completely prevents reaction with moisture and salts, so the manufacturer of such a machine safely gives a guarantee for 8-10 years of absence. through holes. This technology is used on the vast majority of European cars, from cars to large trucks.
A little specifics
The owners of Renault Logan have a logical question: is the metal on this vehicle galvanized? Is it worth worrying about the condition of your car when operating it in cities where aggressive chemicals are used to clean the streets in ice?
If you turn to the official documentation for Renault Logan, you can quickly find lines stating that the Renault Logan body has a zinc layer that meets all European standards. However, the owners themselves claim that on the first generation, the rusting of the arches and the bottom of the doors occurs as quickly as if the metal were not galvanized. What's the matter?
It turns out that the first generation has a number of elements that are not galvanized. Summing up simple statistics, we can draw the following conclusion. About 60 percent of the body, indeed, does not have a zinc layer. Otherwise, the cost of the machine could increase significantly. True, when developing the second generation, this problem was solved, and now the sedan has more than 90 percent of galvanized elements.
Summary
Renault Logan has reliable protection against aggressive external influences and decay. However, an excellent preventive measure is to periodically check the machine and timely conservation of problematic sources. This will repeatedly extend the life of the car and protect the car from through holes.
When buying a car, people must specify whether the manufacturer has provided for galvanizing the body or not. The reasons for this interest are clear.
Galvanization prolongs the life of the metal and reliably protects against corrosion.
What other advantages of galvanizing are worth highlighting? How to determine if the body is galvanized on Renault (Sandero, Logan or Duster), Lada Vesta, Ford Focus, Opel and other models? What methods of galvanizing are in demand? Let's figure it out.
Advantages
The power part of the car is characterized by a large resource, estimated at hundreds of thousands of kilometers. In this case, the weak link is the body.
After 2-3 years of operation, rust appears on it, which requires urgent repair and subsequent tinting problem areas.
To extend the life of metal, car manufacturers and motorists resort to metal galvanization, which provides the following effect:
- Resistant chemical protection against external influences;
- Resistant to moisture and chemicals. The coating of the metal base with zinc guarantees reliable protection of the body and gives the motorist a chance to forget about the problems of operation.
On the other hand, there are a number of disadvantages here:
- Full galvanization is a minus from the standpoint of ecology. Scientists have proven that such coatings are harmful and affect the state of the atmosphere and human health;
- Body elements coated with galvanized sanding and stripping is prohibited. Otherwise, the treated area is instantly covered with a layer of rust.
There are situations when paint lags behind galvanization. It requires the involvement of craftsmen who will remove the necessary layer and properly process the surface.
Recently, a myth has been circulating that galvanized metal does not rust at all. This is not true.
In practice, galvanizing inhibits corrosion, but even without an additional layer of zinc is not a guarantee of salvation.
Few people know, but the zinc layer is a couple of microns, which does not allow protecting the body part from chemistry.
Zinc "shield" of any car, be it Lada Vesta, Ford Focus, Opel or Renault (Logan, Sandero, Duster), decreases over time.
Mechanical damage, such as stone impact, accelerates the corrosion process. But that's not all.
During operation, the metal is subjected to vibrations, shocks, which leads to the appearance of microcracks, dents, which act as an aid to the onset of corrosion.
We must not forget that galvanizing galvanizing is different. Here it is worth highlighting the following options - full or partial, one-sided or two-sided.
At the same time, the methods of applying a protective layer also differ (more on this below).
In addition, each car has a group of hidden elements - racks, boxes and thresholds, where rust appears first.
So the treatment is good only in combination with additional treatment with an anti-corrosion compound.
How is galvanizing done?
As already mentioned, several galvanizing methods have been developed. Among them:
1. Galvanic.
The principle here is to dip the metal elements in a prepared electrolyte with a high zinc content.
The galvanic type of processing is popular with manufacturers in Europe and Japan. But here it is worth highlighting a number of nuances.
Full processing involves the coating of all metal elements of the body.
If there is no such prefix, then only some elements are processed - thresholds, bottom and others that are more susceptible to rust.
But in both the first and second cases, the fact of galvanization is prescribed in the technical specifications.
Parameters of galvanized zinc coating:
- Zinc coating - 5 microns;
- Two layers of soil - 5 and 20 microns;
- Base - 10 microns;
- Lacquer - 20 microns;
- Base - 10 microns;
- Lacquer - 20 microns.
2. Cold galvanized.
This type of processing is considered popular by a number of European and Asian manufacturers.
The principle is a two-stage processing of the body:
- Surface coating with phosphate salts of iron, manganese or zinc;
- Application of primer or paint with the addition of fine zinc to the composition.
Cold galvanizing equates to high quality painting.
Masters say that this method of galvanizing is a marketing ploy. Wherein reliable protection from corrosion in violation of the integrity of the paintwork, it does not.
Characteristics:
- Zinc-containing primer - 10 microns;
- Two layers of soil - 15 and 35 microns;
- Base - 15 microns.
3. Hot dip galvanized.
This type of galvanizing is carried out on one or both sides. At the same time, the application methods protective coating the following:
- Immersion of a body element in a molten zinc solution;
- Applying a protective composition to the body sheet at the stage of rolling.
It is believed that hot-dip galvanizing guarantees the effect and resistance to corrosion. It is popular with manufacturers Ford, Porsche and Volvo.
Options:
- Zinc coating - 12-15 microns;
- Two layers of primer - 20-30 microns;
- Base - 20 microns;
- Enamel - 40 microns;
- Lacquer - 5 microns.
How to find out if the car body is galvanized?
When buying a car, people specify whether a galvanized layer is provided on the body or not.
There are two ways to determine:
1. Using the capabilities of special equipment.
For a single application, this option is not justified, because the cost of the device is high. In fairness, it should be noted that not even all service stations buy such devices.
If the device is at the disposal of the service, then the cost of the check will be such that it is easier to add money and purchase a car whose body is galvanized exactly.
2. Study of technical documentation.
As a rule, manufacturers indicate the presence of galvanization and type. In addition, it is prescribed whether the body is completely galvanized or only partially.
When choosing the second option, consider the following rules:
1. On cheap cars, the method of galvanizing or hot-dip galvanizing is not used due to the high cost of the process;
2. If the manual says that the body is galvanized, then this may indicate the following:
3. The car is galvanized in compliance with the rules only in that situation, if the instructions indicate complete processing.
4. Do not forget to go online and check if the car body is really galvanized or if this is a sales pitch of the seller in order to get rid of the “iron horse”.
Below we consider some models and nuances of galvanization:
- Renault Sandero has a partial bodywork. Type - zinc metal. During processing, a layer of oxides containing zinc elements is applied. Protection is enough for an average of 5-6 years.
- Renault Duster has a partial processing. Type - micrometal. It uses the technique of spraying a layer containing zinc particles or applying protection at the rolling stage. The quality is acceptable, but the first corrosion often appears after 2-3 years.
- Renault Logan. Latest Models, starting from the year 2013, are processed completely. Method - galvanic (two-sided) galvanization. The principle of operation is to immerse body elements in zinc electrolyte and apply current. The final layer of zinc spraying is 9-15 microns. The average service life of a body without corrosion is 7-8 years.
- Hyundai Solaris. The body of these cars is processed by cold galvanizing. The method involves coating with zinc content. The average service life without corrosion is 4-5 years.
- . Since 2014, the manufacturer has been using the method of hot-dip galvanizing of the entire body. The principle is to immerse metal elements in a zinc composition. The finished assembly has a zinc layer with a thickness of 2 to 10 microns. According to the developers, the first traces of rust will appear only after 20-22 years.
There is a lot of discussion about whether the Renault Logan car body is galvanized or not. To understand, you need to have information from the manufacturer.
Car owners often face the problem of painting a car, which becomes apparent even during a break-in (the first year after purchase). As a result, most car owners are wondering if the Renault Logan body is galvanized.
Information from the manufacturer
If you review the information, you can see that the information provided on the Renault Logan manufacturer's website indicates that the car body is fully galvanized. As for painting, the reason for this is indicated by a humid climate, because Renault Logan painting is designed for hot conditions. The developers are actively investigating this problem and will put forward their solution in the near future. On the site http://logan-shop.kz/category/zapchasti/kuzov you can get acquainted with the body of the car Renault Logan.
After buying a car, body corrosion and destruction during operation become an important problem due to the cool climate and frequent precipitation. Why is the issue of galvanization so acutely raised? If the car body is galvanized, then it does not matter - frequent precipitation or not, humid climate or tropical. With a galvanized body, the life of the machine is doubled. Non-galvanized parts break and need to be repaired.
Reviews regarding galvanization
Given the information from the manufacturer, the Renault Logan body is galvanized, but given the short period of operation with the presence of breakdowns, corrosion and other things, the galvanizing of the body is questionable. Renault Logan spare parts need to be changed after the first year of operation, it turns out that old models of cars were only seventy percent galvanized, the rest of the bodies were destroyed under the influence of precipitation and low temperatures. Car owners noted the presence of rust spots and the absence of paint in these places.
To date, the Renault Logan car body has begun to be galvanized by ninety percent, after complaints received and a decrease in the number of sales. If they do a full galvanization of the machine, the cost will increase significantly. Manufacturers, in turn, give a guarantee for fifteen years of operation without the appearance of rust spots. In principle, this is a sufficient service life of the car among other cars. Renault Logan has renewed its reputation and sells quality models.
Is the body of Renault Logan galvanized or not?
The diverse and harsh climate in Russia puts serious demands on car manufacturers for anti-corrosion treatment of their cars. Sudden changes in temperature, high humidity, salt, anti-icing reagents can eat a car body in a few years. For this reason, in order to take a firm place on Russian market, the designers of the Renault Logan car had to thoroughly smash their heads. But first things first.
Renault Logan I generation
The Renault Logan car began its journey on Russian roads in 2005, when it was still quite new model occupied uncertainly automotive market gaining trust from potential buyers. In the first year of serial production of cars, problem areas appeared on a certain percentage of cars in the form of spots and traces of corrosion on various parts of the body.
Problem areas
These turned out to be: wheel arches, trunk opening, windshield frame and parts of the roof under the door seals. And among other things, cracks were found on the paintwork in the area of \u200b\u200bthe joints rear pillars and car roofs. As they say, the first pancake turned out lumpy. However, due to the fact that the release of the new model was widely announced by the media and caused great excitement, such problems in Renault Logan were not only overgrown with many myths and rumors, but sometimes they were completely exaggerated.
One of the most problematic places in old Logan is the doors.
The centers of corrosion appeared on cars produced mainly in the period from 2005 to 2006. Speaking formally, such violations in the paintwork (paintwork) did not require any warranty service, because they appeared after it ended.
Often the doorway begins to rust
However, the fact remains, and real problem has been identified. Then the Renault concern took unprecedented measures to extend the warranty for paintwork, and in order not to lose the trust of customers, it recognized all the facts of corrosion as a warranty case.
car bottom
The bottom of the car practically does not suffer from rust due to the high ground clearance of Logan. Clearance allows you to less cling to bumps in the road and scratch the bottom from potholes.
Solution for full body galvanization
The concern claims that the Renault Logan body is galvanized during production, but many Renault Logan owners do not trust this information.
In order not to experience problems with manufactured cars in the future, it was decided to galvanize almost all external parts.
In addition, for the purpose of additional protection of the body, the technology of “sacrificial anodes” was used, which were installed mainly in the door hinges in the form of inserts and corroded instead of iron. The guarantee for anti-corrosion protection of the car is within 15 years, which is a sufficient period even for cars of a more expensive price segment.
A piece of paint flew off the wing, a galvanized body is visible, but rust still began to appear
The result of the work done by the Renault concern was not long in coming. Rumors about a new budget and inexpensive car, with a galvanized body, quickly dispersed among the people and rightfully lost their claims on the quality of the coating on the Logans. Few modern automakers can boast such a result in the service sector and understanding of the problems of their customers.
7 layers galvanized
- Galvanized body parts on the outside
- cataphoretic soil layer
- Sealing and anticorrosive mastic
- Second coat of primer
- Layers of car paint
- layers of car paint
- Anti-corrosion mastics
Such a puff cake is quite enough to use a generation I car in conditions Russian roads. The vast majority of "Loganovodov" agree on one thing, that additional anti-corrosion treatment for a technically whole body is not required, moreover, it is a waste of money.
Renault Logan II generation
Most owners agree that the Renault Logan body is well galvanized and practically not subject to corrosion.
When designing a radically changed appearance, a 2nd generation Renault Logan car, the designers took a different look at the anti-corrosion treatment of the body.
From 2013 to the present on Renault conveyors, Logan models are subject to full body treatment, including hidden cavities by double-sided galvanizing (greatly combined with paint and primer) using the method of immersion in zinc electrolyte under the influence of current.
Rust on Logan which is less than a year old (under the front right door - under the lining)
With this treatment, the zinc layer is of the order of 9-15 microns. Thus, under normal operating conditions, the first traces of corrosion may appear no earlier than after 10 years of using the car.
Only numbers!
- 5-15 µm (micrometers) is the ideal zinc coating thickness for corrosion protection on a vehicle.
- From 1 to 6 microns - this is the rate of destruction of the zinc layer per year, in case of damage paintwork. Destruction occurs more actively at positive temperatures.
Summing up
Summing up all of the above, you can be sure that most cars P eno Logan on our roads have a galvanized body with a high degree of protection against corrosion. Having such a car, you can be prepared for all the troubles of the Russian climate and operating conditions.
