  • For key and important parts with tensile strength greater than 1034Mpa, the stress should be removed at 200±10℃ for more than 1 hour before plating, and for carburized or surface hardened parts, the stress should be removed at 140±10℃ for more than 5 hours. The cleaning agent used for cleaning shall have no effect on the binding force of the coating and no corrosion on the substrate. Acid activation Acid activation solution should be able to remove corrosion products and oxide film (skin) on the surface of parts without excessive corrosion on the matrix.

  • The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.
