Coating Process: Electro - galvanizing is an electrochemical process. The nuts are immersed in an electrolyte solution containing zinc ions, and an electric current is passed through the solution. This causes zinc ions to deposit on the surface of the nuts, forming a thin, uniform zinc coating.
Function of the Coating: The zinc coating serves several important functions. Firstly, it provides excellent corrosion resistance, protecting the underlying metal of the nut from rust and oxidation. This is particularly important in environments where the nuts may be exposed to moisture, humidity, or corrosive substances. Secondly, the coating can improve the appearance of the nuts, giving them a bright and shiny surface. Additionally, the electro - galvanized coating can also enhance the lubricity of the nut's surface, making it easier to handle during installation.
