In the electroplating industry, chromium plating is a common surface treatment method, which not only provides a decorative bright appearance, but also gives the workpiece good hardness, corrosion resistance and wear resistance. However, the surface roughness of the plating is an important index to measure the quality of the plating, which will directly affect the performance and appearance of the plating. The following are several key factors that affect the surface roughness after chromium plating:
Some customers have asked if aluminum alloy can be chrome plated. Our answer is yes. Chromium plating of aluminum alloys usually requires several complex processing steps to ensure the adhesion and durability of the chromium coating. In this issue, let's take a look at some of the basic steps of aluminum chrome plating:
The alkaline zincate galvanizing process is a common electroplating process used to coat a metal surface with zinc to provide a protective layer against corrosion. In the basic zincate galvanizing process, sodium carbonate is usually added to the basic zincate galvanizing process, which has several functions:
Nickel electroplating process and electroless nickel plating process are both methods to achieve a layer of nickel plating on the surface of metal or other materials, but they have obvious differences in principle and operation:
When using nickel plating additives, the roughness of the metal surface has an effect on the plating in the following ways:
Hard chromium plating additives are chemical substances designed to improve the quality and properties of hard chromium plating. They have the following effects on the coating:
