Screws are a very common component in real life. The use of this component can help us fix two, different components, so as to combine the original scattered components to achieve the purpose of instrument assembly. The use of this kind of parts often faces some problems, among which corrosion and rust are a common problem. Once the screw is corroded and rusted, it will affect the normal opening of the screw on the one hand, and thus affect the maintenance of the instrument. On the other hand, when the screws appear rusty, they will also damage the instrument, causing the instrument itself to pose a safety hazard. The same is true for a car, once the car screws appear rusty, it will affect the maintenance and safety of the car. Therefore, how to prevent corrosion and maintenance of automobile screws is a very important issue.
In actual use, there are four main ways to prevent corrosion of automobile screws. The first aspect is to prevent corrosion through its own materials. To use this method to prevent corrosion, first of all, the material used to make the screw must meet certain requirements. For example, some materials with strong corrosion resistance are used for the manufacture of screws, but in fact, from an economic point of view, unless there are special requirements, this method is used for implementation of anti-corrosion. Corrosion is not particularly feasible. Another anti-corrosion method is to control the use environment. Only with this method, it is required to use the screw in a certain environment. But in fact, the environment of use is often not a choice, unless the environment in which the instrument is used is very suitable for anti-corrosion.
The other two methods of anti-corrosion for automobile screws are bonding the interface between the material and the environment and improving the structure of the screw. The first method mainly needs to be applied to some coatings, especially some coatings that can prevent corrosion, which can effectively help the screw to prevent corrosion. The second method is also a more commonly used method. By improving its structure, the contact surface between the screw and the external environment can often be improved, so as to achieve the effect of anti-corrosion.
