The bodice of the vehicle bodies implies the coating of a metal surface with a substance that contains zinc and can limit the destructive effect of corrosion. However, the bodice galvanized is a rather complicated process from the technology, as well as labor-intensive, troublesome and expensive.

Nevertheless, the galvanized of the body is often used and developed all the time, in particular, foreign road companies are engaged in this, covering their vehicles with a protective substance for several decades. Special attention to galvanized, is explained by a number of advantages obtained by the car body as a result of appropriate processing.

If the body of the vehicle is performed qualitatively, it gives up to 80% of the guarantee of its long life. Therefore, the galvanization of the automotive corps (complete or partial) is when it acquisitions is quite important characteristic. The galvanizing the body of the car or its parts is used in foreign countries for a long time, and to be more accurate, then more than thirty years. Domestic manufacturers also do not stand still and gradually introduce such technologies. However, a lot of supported cars or economic vehicles do not have such protection. That is why most drivers are often wondering how to produce a vehicle bodice galvania on their own. And if not completely, then at least some elements that are most vulnerable before the influence of the aggressive environment.

Galvanized as a way of protection against corrosion

The main advantage of galvanized is its resistance to corrosion influence. The zinc layer directly does not respond to the effect of salts and moisture, constantly attacked metal. It is capable of creating a certain barrier that protects steel from the destructive effects of the aggressive environment.

In addition, it is worth saying about the durability of such a coating, since no other corrosion treatments are capable of compared with a zinc coating along the service life.

Most highway companies are building the body of their cars at the stage of production. Some of them produce such processing over the entire surface of the car body. Others - only some details zinc. In addition, some of them produce galvanizing several elements completely, while others are only on the one hand. For example, in this way, the body of Lada viburnum of domestic production and the model of some European manufacturers are treated.

It is much easier to bring the car body in order right away, than all the time it is repaired and straighten. Yes, and galvanized is much cheaper than a new automotive case. The most vulnerable element in the vehicle is its bottom, on this car manufacturers are most often subjected to this item to this item. For this, they are applied anodic protection - this is a metal having a smaller electrochemical potential in comparison with the metal of the automotive housing. The most suitable for this is zinc, as it has a relatively low price and high physico-chemical properties.

Galvanic galvanizing

Electroplating galvanizing is made by the method of extracting the finished part entirely in the bath, which contains a zinc electrolyte. Thus, the current effects on zinc, and it sticks to the metal surface of the element. At the same time, the part is connected directly to the minus electrode, and the bath housing is to the positive.

Cold zinc

The process of cold galvanizing is very similar to the previous one. Only the element is not immersed in the bath or other capacitance of the corresponding dimensions, but are treated with an electrode containing zinc, which is also connected to the positive power supply terminal. This method is much cheaper, but is less reliable. As a rule, cold galvanized apply on economy class cars.

Thermal diffusion galvanizing

This type of galvanized is the immersion of the body or separate element into the appropriate container, which contains a special zinc solution heated to the required temperature. It can be performed both on one side of the hull and from two. In addition, there is a method on which the zinc melt is applied to a metal sheet during rolling. Thermal galvanizing is mandatory passing cars of the following brands - Porsche, Volvo, Ford and GM. It is quite effective and is capable of protecting the vehicle from corrosion for a long time.

Safety when working with galvanized

First, such a procedure must be carried out in the fresh air, away from various foci of ignition.

Secondly, when cleaning the surface of the body from rust or other contaminants, it is strictly forbidden to use the rust shredder or orthophosphoric acid for this.

Thirdly, during the galvanizing of the body, it is necessary to comply with elementary safety rules when working with electricity and chemical solutions.

In addition, when preparing a solution, you need to protect your hands, eyes and respiratory organs.

Thermal diffusion galvanizing details with their own hands

The thermal galvanizing of the body has a very complex technology and it is impossible to perform it independently at home.

Galvanic galvanizing the body with their own hands, the course of work in stages

To produce body galvanizing with a galvanic method, it is necessary to prepare a special solution for galvanizing, which you can easily do yourself without necessarily following the safety rules. For this, it is necessary to purchase pure zinc and sulfuric acid, which can be easily bought in stores for radio amateurs or in the car market. In addition, you will need the optimal capacity, resistant to acid and power supply, such as a conventional charger or car battery.

To prepare a zinc-containing solution, it is necessary to put a piece of zinc in a pre-prepared container - one liter of sulfuric acid accounts for about 400 grams of metal. Then, it is required to pour acid into the container gradually and small doses.

At absolute dissolution of zinc, it is necessary to check whether the acid was reacting, for which it is necessary to lower a small piece of zinc into the solution. If you have not seen the reaction, during which hydrogen bubbles are distinguished, it means that the solution is fully prepared for use. By the way, such a composition can be applied not only for galvanic galvanizing, but for galvanized by the cold method. At the final stage of the preparation of the solution, a clear solution from the sediment should be separated.

Also, do not forget to prepare the surface of the body, for which it is necessary to remove traces of corrosion, dirt and old paint. As mentioned above, the aggressive formulations should not be used for this, it is better to clean the body with a skin or aqueous solution of soda.

Next, we take an element that needs a galvanized, and connect a negative terminal of the current source, and the positive terminal connects to the container. Whatever the galvanizing has passed successfully, voltages at 12 volts and current strength in one amp will be enough. If the procedure proceeds in the right way, an uniform gray layer will appear on the part, if the process is too fast - the surface of the element can become dark and loose. To neutralize the acid that remains after the galvanizing, the element in conventional water or drinking soda should be flushed.

If you need to galvanize a large part or the entire body, you need to wrap a small piece of zinc several times with a cloth. It should be connected to a wire that is connected to a plus source. At the same time, minus connect to the "mass", that is, to the body of the vehicle. You can connect wires using "crocodiles" to cure. However, the fabric in which we wrapped zinc should not touch them.

Further, wrapped in zinc tissue, omit in the solution and drive them along the plots that need to be galvanized, thus, metal is mounted on the body surface. At the end of the procedure, you need to wash the place with water and dry.
