Electroless nickel plating is a process in which a nickel layer is deposited on the surface of a material without an impressed current. The main purposes of heat treatment after electroless nickel plating are as follows:
The quality of tin plating additives has a direct relationship with the color of tin layer and the overall coating quality. Poor quality tin plating additives can cause the following problems, which can affect the coating to appear yellow:
The service life of electroless nickel plating solution is largely affected by a number of factors, such as the type of plating solution, working conditions, coating quality requirements, and the maintenance and management of plating solution. The service life of the electroless plating solution can range from a few months to a year or even longer. The following are some key factors that affect the service life of electroless nickel plating solution:
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:
Tin plating brightener is a chemical substance added to the tin plating solution to improve the appearance and quality of the coating. Its influence on the weldability of tinplating layer is mainly reflected in the following aspects:
Turbidity in electroless nickel plating solutions can be caused by a variety of reasons. The following are some of the common causes of cloudy electroless nickel plating solutions:
