Nickel sulfamate plating is a widely used plating process in industrial production, where the core objective is to obtain nickel coatings with high bonding strength and excellent physicochemical properties. In practice, the use of additives has a significant impact on the bonding strength of the plated layer. In this issue, we take a closer look at this issue.
In the bright nickel plating process, the use of nickel plating brightener is one of the key factors, they are usually divided into primary brightener and secondary brightener, each of which has its own specific function and role.
In the pyrophosphate copper plating process, the Hull cell test is a conventional method used to evaluate the performance of plating solutions and process parameters. However, when the bright area of the test piece plating is on the small side, it may suggest some potential problems that need to be emphasized and solved.
Zinc-nickel alloy coatings are widely used in many industrial applications due to their excellent corrosion resistance, high hardness and good decorative properties. Black passivation is a surface treatment process that provides better protection for zinc-nickel alloy coatings and gives them an attractive black surface. However, during the black passivation process, the surface of the coating is prone to coloration, which affects the appearance and corrosion protection. The coloration is caused by the non-uniformity of the passivate layer and is usually due to the following reasons:
After zinc-nickel alloy plating, colored passivation is often intended to improve corrosion resistance and add aesthetic appeal. However, poor results when performing salt spray testing can stem from several key factors:
Plastic plating is a method of imparting a metallic appearance and performance to a plastic substrate by depositing a metallic coating on it. Roughening is a key step in the plastic plating process and is critical to the quality of the final coating. However, inadequate roughening can cause a number of problems that affect the performance and appearance of the final product. In this article, we explore the effects of insufficient roughening.
