The quality judgment on the surface treatment of DIN 603 bolts is mainly to check whether the corrosion resistance of DIN 603 bolts is effectively increased and whether the increase is not by the expected requirements. Electroplating, hot-dip galvanizing, and mechanical plating on the DIN 603 bolts are the most common methods. Here we share the DIN 603 bolts surface treatment:
1, DIN 603 bolts plating
Electroplating of DIN 603 bolts means that the part of the DIN 603 bolts to be electroplated is immersed in a specific aqueous solution which contains some deposited metal compounds so that after passing through the aqueous solution by an electric current, the metal substance in the solution is deposited and adhered to to the immersion part of DIN 603 bolts.
2, mechanical plating of DIN 603 bolts
The mechanical plating of DIN 603 bolts to refer to the impact on DIN 603 bolts on the surface of the DIN 603 bolts using specific physical and chemical means so that the coated metal forms a coating on the surface of the DIN 603 bolts by cold welding to the surface. Processing effect.
3, hot-dip galvanizing of DIN 603 bolts
The hot-dip galvanizing of DIN 603 bolts is to immerse the carbon steels DIN 603 bolts in a bath of molten zinc with a heat of about 510 ° C so that the iron-zinc alloy on the surface of the DIN 603 bolts are converted into passivated zinc. Get a surface treatment effect.
DIN 603 bolts surface treatment is commonly used in the above three methods, we use the above DIN 603 bolts surface treatment method, I hope to help everyone.
