The quality of the surface treatment of Full Threaded Stud is mainly to check whether the corrosion resistance of Full Threaded Stud is effectively increased, and whether the increase is in line with expected requirements. After the surface treatment of the Full Threaded Stud, it can present a more beautiful appearance, and the corrosion resistance of the Full Threaded Stud itself will be improved. The main purpose is to make the Full Threaded Stud itself have anti-corrosion ability to increase the reliability and adaptability of the Full Threaded Stud.
1. Electroplating of Full Threaded Stud
The electroplating of Full Threaded Stud refers to immersing the part of the Full Threaded Stud that needs to be electroplated into a specific aqueous solution. The aqueous solution will contain some deposited metal compounds, so that after the current passes through the aqueous solution, the metal substances in the solution are deposited and adhered to On the immersion part of the Full Threaded Stud. Electroplating of Full Threaded Stud generally includes zinc plating, copper, nickel, chromium, copper-nickel alloy, etc.
2. Hot dip galvanizing of Full Threaded Stud
The hot-dip galvanizing of Full Threaded Stud is to immerse Full Threaded Stud with carbon steel composition into a bath of molten zinc with a heat of about 510°C, so that the iron-zinc alloy on the surface of Full Threaded Stud will be converted into passivated zinc. Obtain the surface treatment effect.
- Mechanical plating of Full Threaded Stud
The mechanical plating of China Fasteners refers to the use of specific physical and chemical means to impact the surface of the Full Threaded Stud with the powder of the coated metal, so that the coated metal is cold welded to form a coating on the surface of the Full Threaded Stud to achieve surface treatment effect. The mechanical plating of Full Threaded Stud is mainly applied to spare parts such as screws, nuts and washers.
