DIN 603 Bolt Surface Treatment

  1. Electroplating of DIN 603bolts

Electroplating of DIN 603 bolts means that the parts of the fastener that need to be electroplated are immersed in a specific aqueous solution, which contains some deposited metal compounds, so that after passing through the aqueous solution by electric current, the metal substances in the solution are deposited and adhered to The immersed portion of the fastener. Plating of DIN 603 bolts generally includes galvanizing, copper, nickel, chrome, copper-nickel alloys, and the like.

  1. Hot dip galvanizing of DIN 603bolts

The hot dip galvanizing of DIN 603 bolts is to immerse the DIN 603 bolt of carbon steel into the bath of molten zinc with a heat of about 510 ° C, so that the iron-zinc alloy on the surface of the DIN 603 bolt will be converted into passivated zinc. Get a surface treatment effect. Hot dip galvanizing of DIN 603 bolts is more expensive than electroplating.

  1. Mechanical plating of DIN 603bolts

Mechanical plating of DIN 603 bolts refers to the impact of the surface of the fastener by a specific physical and chemical means, with the powder of the coated metal, so that the coated metal forms a coating on the surface of the fastener to form a surface. Processing effect. Mechanical plating of DIN 603 bolts is mainly suitable for spare parts such as screws, nuts and gaskets.

The surface treatment of DIN 603 bolts, the main purpose is to make the fastener itself corrosion-resistant to increase the reliability and adaptability of DIN 603 bolts. Therefore, the quality judgment of DIN 603 bolt surface treatment is more important. Whether the corrosion resistance of the DIN 603 bolt is effectively increased and the magnitude of the increase meets the expected requirements.
