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:
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:
In acid zinc plating process, the concentration of zinc ions is an important factor affecting the quality of the coating, which directly affects the adhesion, crystal structure, gloss and corrosion resistance of the coating. The following are several possible effects of zinc ion concentration on coating quality:
The brightness of an electroplated black zinc passivation coating is influenced by a number of factors. A passivation coating is a thin conversion coating applied after electroplating that provides additional protection against corrosion and imparts a certain color and luster to the metal surface. The following are some of the factors that may affect the brightness of an electroplated black zinc passivate coating:
In the production process of barrel nickel plating, it is very important to control the concentration of various chemical components to ensure the quality and uniformity of the electroplating. Nickel sulfate is a common nickel source in nickel plating process, and its concentration in plating solution has a direct influence on plating process. If the concentration of nickel sulfate is too high, it will produce a series of adverse effects.
