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:
Sulfate bright tin plating is a plating process for metal surface treatment that uses a plating solution with sulfate as the main component to deposit a layer of bright tin on a metal surface. Bright tin plating is widely used in the electronic, electrical, automotive and construction industries to provide good electrical conductivity, corrosion protection and beautiful decorative effects.
Tin plating brighteners are additives used in the tin plating process that have a significant effect on the roughness of the tin plated layer. The mechanism of action of brighteners usually involves influencing the way the crystals of the plated layer grow, inducing the formation of finer, more homogeneous grains, which in turn gives the plated layer a better appearance, smoothness and finish. Below are a few specific effects of tin brighteners on the roughness of the plated layer:
Acid copper plating process is a plating process that uses an acidic copper sulfate solution as the electrolyte. The process utilizes a DC power source to deposit a thin layer of pure copper on a metallic or conductive surface. Acid copper plating is often used to improve the conductivity of a product, enhance its appearance and increase corrosion resistance.
