Popular Methods to Protect Cars from Corrosion

Whatever the model of car, over time, every car owner is faced with corrosion of the vehicle body. The car body is constantly exposed to a number of factors: temperature changes, air pollution, salt and sand on the road, etc. There are three types of corrosion of the car, namely: chemical, electrochemical and mechanical.

Popular Methods to Protect Cars from Corrosion

Automobile chemical corrosion occurs due to oxidation of metal parts under the influence of the environment, and electrochemical — under the action of water and impurities contained in it. If, in the first two types of corrosion, the metal surface is also subjected to vibrations or increased friction, then mechanical corrosion occurs. The most common type of corrosion for cars is electrochemical corrosion. Especially increases the risk of rust in winter, when sand or salt is sprinkled on the roads. As is known, there are a number of impurities in their composition, which, upon contact with water (snow, rain), dissolve and form electrolytes that negatively affect metal surfaces.

To prevent car corrosion, it is necessary to constantly monitor the condition of the body and carry out anti-corrosion treatment (for example rust inhibitor spray). The most effective way to combat rust is galvanization. It allows you to protect the car not only by electrochemical, but also by barrier method. Body galvanizing can be replaced with the use of a cathode protection devices. The basis of its action is the principle of metal polarization. In the process of polarization, a galvanic couple is formed between the electrode and the metal, and due to the negative charge transmitted by the iron from the device, it does not oxidize. This method is especially effective with regular use of the device.

To slow the wear process of car body panels, you can cover them with a special polymer film. This …
