Electroless nickel plating is a widely used surface treatment technology that provides materials with excellent corrosion resistance and good mechanical properties. However, the performance of the plated layer does not only depend on the nickel plating process itself, but the post-plating treatment process is also an indispensable part. In this paper, we will discuss the post-processing of electroless nickel plating, including passivation, dehydrogenation of the plated layer and heat treatment, and illustrate how electroless nickel concentrate Ni-809 improves the quality of the plated layer.
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.
Alkaline zincate galvanizing process is a common electroplating process used to coat metal surfaces with zinc to provide a corrosion-resistant protective coating. In the alkaline zincate galvanizing process, sodium carbonate is usually added to the alkaline zincate galvanizing process and it serves several purposes:
Sulfate matte tin plating process occupies an important position in the field of electronic packaging and is widely used for its excellent conductivity and oxidation resistance. However, in practice, the leakage of plating is an urgent problem to be solved. In this paper, we will discuss the causes of leakage plating and the corresponding solutions.
Acid bright tin plating is an important process widely used in the manufacture of electronic, electrical and communication equipment. However, in the actual production process, we often encounter the phenomenon of whitening of plating, which not only affects the aesthetics, but also may adversely affect the functionality. So, what are the reasons for the whitening of the plating layer and how to solve it?
Semi-bright nickel plating is a very common type of nickel coating in the plating industry, which is intermediate between bright nickel and non-glossy (matte or dull nickel), and is intended to provide a surface coating that meets certain mechanical and industrial performance requirements while also having a certain aesthetic appeal. Typical characteristics of semi-bright nickel include a more uniformly smooth surface and a moderately light-reflective gloss, but not as highly reflective and mirror-like as bright nickel.
