Screw processing - surface treatment

Self tapping screw surface treatment through a certain process on the workpiece surface to form a layer of corrosion resistance but also beautiful appearance of covering layer. Surface treatment can have several kinds method, respectively is: electroplating, galvanizing and mechanical plating. First: to speak plating plating parts soaked in containing deposition of metal compounds in aqueous solution, and then to the current through the plating solution, plating metal precipitation and deposition to the parts. Tell hot-dip galvanizing: will need galvanized parts dip in the temperature of approximately 510 degrees C melt zinc, which makes the steel parts on the surface of iron zinc alloy gradually into the product on the surface of the passivation of zinc. Finally, through mechanical plating: coating metal particles to impact the product surface, and coating on the surface of cold welding products.
