Automobile is a common means of transportation and has become an indispensable means of transportation for urbanites. An important part of the automobile industry - the anti-corrosion process of steel base parts is also developing continuously, and various types of anti-corrosion treatment methods have emerged - For example Dacromet metal coating process.
Dacromet metal coating has been widely used as an anti-corrosion process for auto parts. This process has gradually replaced electro-galvanizing and physical coatings, and has been more and more widely used. So what are the advantages of this process? What? Next, we will ask the technical staff of the Dacromet manufacturer to introduce to you:
1. Dacromet coating has good anti-corrosion protection for heat-resistant load parts. Some auto parts have high operating temperature, and the surface protection layer of these parts needs to have good corrosion resistance at high temperature. The curing temperature of Dacromet coating About 300 degrees. The chromic acid polymer in the coating does not contain crystal water, the coating is not easy to damage at high temperature, and has certain high humidity and corrosion resistance.
2. Dacromet metal coating is more suitable for anti-corrosion of high-strength steel parts. There is a risk of hydrogen embrittlement in pickling and electroplating of high-strength steel. Although hydrogen can be driven by heat treatment, it is difficult to completely drive hydrogen. Dacromet The Luo coating process does not require pickling and activation, does not cause electrochemical reactions of hydrogen evolution, and avoids hydrogen embrittlement, so it is especially suitable for anti-corrosion of high-strength steel parts and other components.
To sum up, the Dacromet metal coating process has the advantages of corrosion resistance, heat resistance, weather resistance, and no hydrogen embrittlement. It is suitable for the corrosion protection of certain industrial metal parts, such as the corrosion protection of special automotive parts. Extend the life of the car.
