Electroless nickel plating is an important surface treatment technology. Unlike conventional electroplating processes, electroless nickel plating does not require an applied electric current and forms a homogeneous, compact nickel-phosphorus alloy layer on the surface of the workpiece through a chemical reduction reaction. The properties of this coating can vary depending on the phosphorus content, thus playing a crucial role in different industrial applications.
In the electroplating industry, trivalent chromium blue-white passivates are widely used to enhance the corrosion resistance and aesthetics of zinc and its alloy surfaces. The color of the passivation film not only affects the appearance of the final product, but also indirectly reflects the quality of the film. Below are a few key factors that affect the color of trivalent chromium blue-white passivate films.
The slow deposition rate of the chromium electroplating process can be specifically analyzed from the following electrochemical and process parameter perspectives:
In the production process, we will find that many tinned electronic plug-ins will appear tinplating discoloration after high temperature welding, and the workpiece can effectively prevent the plating discoloration by adding a high temperature nickel plating process before tinning. So which high temperature nickel additive should we choose?
The corrosion resistance of nickel sulfamate plating layers can be influenced by a number of factors. In order to improve the corrosion resistance of nickel plating layers, the following key factors need to be managed and controlled:
The nickel electroplating process is highly favored in the industrial and manufacturing sectors, especially because it provides a coating that is significantly more resistant to wear. The coating produced by nickel plating forms a dense, uniform metallic layer that protects the base material and reduces friction, thereby reducing wear.
