  • The key and important parts with tensile strength greater than 1034Mpa should be relieved of stress at 200±10℃ for more than 1 hour before plating, and the carburized or surface hardened parts should be relieved of stress 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.

  • Galvanizing can be done by zincate galvanizing or chloride galvanizing. Appropriate additives shall be used to obtain a coating that meets the requirements of this standard. Luminescence treatment should be carried out after luminescence plating. The parts that need to be dehydrogenated for passivation should be passivated after dehydrogenation. Before passivation, 1%H2SO4 or 1% hydrochloric acid should be applied to activate 5~15s. Passivation shall be treated with colored chromate unless otherwise specified in the design drawings.
