With the popularization of Dacromet, there are more and more places around us that use the technology of Rockwell, the advantages of the technology are very obvious, but the small series think it is not enough, because different products in the production of our production quality requirements are not the same, we will take a look at the process of the Rockwell coating, Where improvements are needed.
Dacromet setting contains the environment, and the human body harmful chromium ions, especially hexavalent chromium ions, no matter what chemical additives, or anti-corrosion of the solution is more or less harmful to the use of the appropriate is more important.
Dacromet coating on the surface of the single color only silvery white, and silver gray is not suitable for automotive development personalized needs. However, different colors can be obtained through the reprocessing or composite coating to improve the decorative and matching of the parts of the truck. The conductivity of Dacromet coating is not good this is not suitable for conductive parts, due to the electrical conductivity of the problem, so in some anti-corrosion work we will not adopt this approach. Dacromet's surface hardness is not high, wear resistance is not good, and the products of the Rockwell coating is not suitable for copper, magnesium, nickel and stainless steel parts contact and connection, because they will produce contact corrosion affects the quality of the product surface and anti-corrosion performance. Dacromet has higher sintering temperature and longer energy consumption. This requires us to control the temperature of the Nile in the process of the processing of Rockwell, where the high temperature of the equipment needs to be improved is not good for surface treatment.
