  • Electro-galvanizing is a commonly used anti-corrosion treatment process that protects the substrate from corrosion by depositing a zinc layer uniformly on the metal surface through electrolysis. In order to further improve the corrosion resistance and appearance quality of the galvanized layer, a passivation treatment is usually applied after electro-galvanizing. An important category of passivation is the colorful galvanizing passivate, which provides additional protection to the coating while giving the metal surface a variety of colors that are aesthetically pleasing and practical.

  • Electrolytic degreasing in electroplating production is a pretreatment process that utilizes an electrolytic process to remove grease and organic contaminants from the surface of metal workpieces. Cleaning the metal surface prior to plating is critical, as oil and grease can hinder the uniform deposition of the plating layer and may lead to quality problems such as peeling and flaking of the plating layer. Electrolytic degreasing powder is a chemical agent used in industrial production to remove grease and other impurities from metal surfaces, mainly by electrolysis. The following factors should be considered when selecting a suitable electrolytic degreasing powder:

  • Blackening of nickel plated workpieces in air is not usually a normal phenomenon, and may be caused by oxidation or sulfidation of the nickel plated surface. Nickel plating usually has good corrosion and oxidation resistance, but under certain circumstances, such as insufficient quality of plating, presence of contaminants in the environment, high humidity, or poor storage conditions, the surface of nickel plated parts may become discolored or blackened.
