• Trivalent chromium black zinc passivation process is widely used in the surface passivation treatment of galvanized layer, which aims to improve the corrosion resistance and corrosion resistance of the coating. However, in practical application, we often encounter the situation of unqualified salt spray test. According to the relevant research, as well as combined with the practical application, we can analyze the reasons for the unqualified salt spray of trivalent chromium black zinc passivation from the following aspects.

  • Matte tin plating is a widely used electroplating process used to deposit a uniform layer of tin on metal surfaces to provide corrosion protection, increase solderability and enhance appearance. This tin layer has a certain "matte" or "non-glossy" effect, as opposed to shiny tin plating, and is characterized by the following:

  • The high-temperature nickel plating process is an industrial surface treatment technology that involves depositing a nickel coating on the surface of a metal or other material. The main purpose of this treatment technique is to improve the corrosion resistance, abrasion resistance, and high temperature resistance of the material, as well as to improve its surface finish. Below are a few important roles and application areas of the electroplated high temperature nickel process:

  • 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:
