When we use high-speed bright tin plating additives, we always come across such problems as easy discoloration and turbidity of the plated layer, uneven color of the plated layer and so on, and the existence of these problems will seriously affect the quality of the plated layer and the efficiency of production. Today we would like to introduce a reliable high-speed bright tin plating additive Sn-819.
Chrome plating is a common surface treatment in the electroplating industry, which not only provides a decorative bright appearance, but also gives the workpiece good hardness, corrosion and wear resistance. However, the surface roughness of the plated layer during the plating process is an important indicator of the quality of the plated layer, and it will directly affect the usability and appearance of the plated parts. The following are several key factors that affect the surface roughness after chromium plating:
When we use nickel sulfamate additives in the production process, a certain amount of internal stress is generated when the crystallization of the plated layer is changed. When the internal stress of the plating layer is large, the hardness of the plating layer is large, easy to peel, crack, and poor ductility. So, what are the factors that affect the internal stress of the plating layer?
The failure of yellowing after plating in the barrel nickel plating process in electroplating plant will undoubtedly increase the difficulty of delivery, whether it is the delay of production schedule or the waste of raw materials, it is a loss. So in addition to the yellowing of the water imprint and the yellowing of the pinhole, what other reasons can cause yellowing after plating?
Yellowing of zinc-nickel alloy plating in the low current region is usually related to process parameters, bath composition and operating conditions. The following are a few possible causes of yellowing in the low current region:
Wetting agents play an important role in the bright sulfate copper plating process , mainly used to reduce the surface tension, so as to improve the contact between the bath solution and the surface of the object to be plated, to enhance the fluidity of the solution and to prevent the adhesion of air bubbles on the surface of the workpiece. Failure to add a wetting agent to the bright sulfate copper plating bath can lead to a variety of plating failures.
