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:
Electroless nickel plating is a commonly used surface treatment technique to improve the corrosion, wear and hardness of a base material by forming a nickel-phosphorus alloy coating on its surface. Maintaining the stability and activity of the electroless nickel plating solution is critical in this process. In this paper, we will discuss how to effectively maintain the electroless nickel plating solution in production.
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.
