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.
In the nickel electroplating production, the big consumption of barrel nickel brightener will undoubtedly increase the cost of production, so it is necessary to understand the causes of such phenomena.
Adjusting the pH of the copper pyrophosphate plating process is a factor in ensuring the quality and performance of the plated layer, and we need to use a number of specific chemicals for careful pH regulation to meet different plating needs.
Zinc-nickel alloy plating has been put into production applications in the field of electroplating production due to its good corrosion resistance, high wear resistance and other advantages. In order to ensure the quality of the plated layer, the zinc-nickel alloy plated product usually needs to be passivated, of which black passivation is a very important method. Bigely zinc-nickel alloy black passivator plays a major role in electroplating production in the following ways:
The phenomenon of color difference in the zinc-nickel alloy plating process is usually related to several factors, including the composition of the plating solution, plating parameters, the surface condition of the workpiece, and the post-treatment process. In plating practice, the problem of color difference is a common quality control challenge, which directly affects the appearance quality of the plated layer.
Electroless nickel plating is an important surface treatment technology. Unlike conventional electroplating processes, electroless nickel plating does not require an applied electric current and forms a homogeneous, compact nickel-phosphorus alloy layer on the surface of the workpiece through a chemical reduction reaction. The properties of this coating can vary depending on the phosphorus content, thus playing a crucial role in different industrial applications.
