In modern industrial products, it is indispensable to use various metal materials as raw materials for product production. However, different types of metals have different chemical properties, so in order to improve the service life and structural performance of metal products, some more active metal products such as copper, aluminum, iron Additional surface anti-corrosion treatment is required. The following editor will introduce you to the common types of metal surface treatment.
1. Dacromet coating surface treatment
Dacromet coating has the advantages of high corrosion resistance, high heat resistance, high weather resistance, no hydrogen embrittlement, etc., which can prolong the service life of the car.
2, electrochemical surface treatment
Including anodic oxidation, electrochemical polishing, electroplating, etc. These treatment methods use electrolysis to achieve the purpose of anti-corrosion treatment of metal surfaces.
In addition to the above two common metal surface treatment methods, the methods we are still using now include mechanical surface treatment such as grinding, painting and other methods. However, I believe that with the development of science and technology, people will also invent More types of metal corrosion protection methods.
