What are the surface treatment amplification of standard parts? It is not unknown to people in this industry. Today zhejiang weigao Industrial Bolt Factory will give you a brief introduction to the surface treatment methods of standard parts:

       1. Electroplating of standard parts

       Standard part plating refers to immersing parts of fasteners that need to be plated into a specific aqueous solution. The aqueous solution will contain some deposited metal compounds. In this way, after passing current through the aqueous solution, the metal substances in the solution will precipitate out and adhere to the tight The immersion part of the firmware. The electroplating of standard parts generally includes zinc plating, copper, nickel, chromium, copper-nickel alloy, etc.

       2. Hot dip galvanizing of standard parts

       The hot dip galvanizing of the standard parts is to immerse the standard parts of carbon steel components into the molten zinc plating bath with a heat of about 510°C, so that the iron-zinc alloy on the surface of the standard parts will be converted into passivated zinc to obtain surface treatment effect. The price of hot dip galvanizing for standard parts is higher than that of electroplating.

       3. Mechanical plating of standard parts

       The mechanical plating of standard parts refers to the use of specific physical and chemical means to impact the surface of the fastener with the powder of the coated metal, so that the coated metal forms a coating on the surface of the fastener by cold welding to achieve surface treatment effect. The mechanical plating of standard parts is mainly suitable for spare parts such as screws, nuts and washers.

       The main purpose of the surface treatment of China Stud Supplier standard parts is to make the fastener itself obtain anti-corrosion ability to increase the reliability and adaptability of the standard parts. Therefore, the quality judgment of the surface treatment of the standard parts is mainly to check Whether the anti-corrosion ability of standard parts is effectively increased, and whether the increase is in line with the expected requirements.
