Surface Treatment Method of Bolts

2021-07-22

Electroplating, hot-dip galvanizing, and plating of mechanical equipment on the surface of bolts are widely used methods. The whole process of creating a soil layer on the surface of the bolts. After the bolts undergo surface treatment, they can show a more beautiful and generous surface. Fasteners Its own corrosion resistance will gradually improve. The more critical purpose is to make the fastener itself have corrosion resistance, so as to improve the credibility and adaptability of fastener application.

Surface treatment method of bolts

1. Electroplating of bolts means to infiltrate a part of the fasteners that must be electroplated into a special solution. The solution will contain some accumulated metal material chemical substances, so that the metal material in the aqueous solution is based on the current amount according to the solution. The chemical substance dissolves and adheres to the penetrating part of the fastener. The electroplating of bolts generally includes hot-dip galvanizing, copper, nickel, chromium, copper-nickel alloys, etc.

2. Hot-dip galvanizing of bolts is to infiltrate fasteners with carbon steel components into the plating tank of molten zinc with a degree of attention of about 510℃, so that the iron-zinc alloy material on the surface of the fasteners will change to passivation Treatment of zinc, and then get the actual effect of surface treatment.

3. The mechanical equipment plating of bolts means that the powder of the coated metal material is used to impact the surface of the fastener according to the special physics and organic chemistry method, so that the coated metal material will be fastened according to the cold welding method. The surface of the piece has a plating layer to achieve the actual effect of surface treatment. The key to the mechanical equipment plating of fasteners is suitable for accessories such as screws, screw caps and gaskets.
