Electroplating is the entire electrochemical process, the entire redox process. The entire process of spring electroplating involves immersing the spring in a metal salt solution as the cathode and a metal plate as the anode, receiving direct current, and depositing the necessary coating on the part. Spring electroplating is one of the basic operations before leaving the factory, which immediately changes the appearance of the spring. The electroplating protective layer can not only prevent corrosion of the spring, but also improve its appearance. Some electroplated metals can improve the working characteristics of springs, but often due to customer requirements, spring factories must electroplate twice as much spring. However, when they come back, they must first clean the surface coating, spring, and then electroplate twice. What impact does this have on the spring?
- The wire washing diameter is small, the wire washing spring force is small, and the wire washing diameter is small.
- The material has become worse. During the pickling process, material defects can be cleaned to a larger size.
- Hydrogen embrittlement. If the entire pickling process is not handled properly, hydrogen embrittlement often occurs.
- If the non-compliance is not too serious, it is recommended not to remove the coating. However, if the hazards of removing the coating are not easily controlled properly, such as the use of critical springs, they must not be reused.
