Spring blade is a common component in the fields of automobile, railway, machinery manufacturing, etc. It has the advantages of good elasticity, strong wear resistance, light weight and so on, and is widely used. However, because the spring is often in a harsh working environment, such as high humidity, corrosive environment, etc., it is particularly important to carry out anti-corrosion treatment for the spring. This article will be combined with the current common spring anti-corrosion treatment methods, for everyone to make a brief review.

The previous common anti-corrosion treatment method is spray anti-corrosion treatment. The method is to use the spray machine to evenly spray the anti-corrosion coating on the surface of the spring sheet to form a protective film to prevent the spring sheet from being corroded. This method is simple and easy, and can meet the anti-corrosion requirements of spring sheet.

The second common method is immersion preservative treatment. In this method, the spring plate introduces the anti-corrosion coating into its surface by soaking, forming a more uniform and complete anti-corrosion film. This method can improve the anti-corrosion performance of the surface of the spring sheet to a certain extent.

The third method is hot dip galvanizing anti-corrosion treatment. This method is mainly to dip the spring sheet into the preheated zinc liquid, after a certain time, zinc will form a layer of white and silver outer layer on the surface of the spring sheet to prevent oxidation. This treatment method has good anti-corrosion effect and long life, so it is widely used in automobile, machinery manufacturing and other fields.

The fourth method is based on electrophoretic preservative treatment. Electrophoretic anticorrosion technology is to use anode anticorrosion mold to guide the embalming fluid to form a protective film in the electrolytic cell and cover the surface of the spring plate. Because the method has the advantages of good anti-corrosion effect and environmental protection, it is adopted by more and more enterprises.

The fifth method is to produce new materials anticorrosion technology. By changing the structure and chemical composition of the material, this technology makes the surface of the spring sheet have certain corrosion resistance, so as to realize the effect of anti-corrosion of the spring sheet by chemical means.
