After zinc-nickel alloy plating, colored passivation is often intended to improve corrosion resistance and add aesthetic appeal. However, poor results when performing salt spray testing can stem from several key factors:
Plastic plating is a method of imparting a metallic appearance and performance to a plastic substrate by depositing a metallic coating on it. Roughening is a key step in the plastic plating process and is critical to the quality of the final coating. However, inadequate roughening can cause a number of problems that affect the performance and appearance of the final product. In this article, we explore the effects of insufficient roughening.
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.
The use of brighteners in metal finishing processes, especially in potassium chloride galvanizing, is essential for achieving high-quality, attractive coatings. Brighteners not only significantly improve the gloss of the coating, but also its microstructure, which affects the overall properties of the coating.
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:
Chrome plating is a common surface treatment in the electroplating industry, which not only provides a decorative bright appearance, but also gives the workpiece good hardness, corrosion and wear resistance. However, the surface roughness of the plated layer during the plating process is an important indicator of the quality of the plated layer, and it will directly affect the usability and appearance of the plated parts. The following are several key factors that affect the surface roughness after chromium plating:
