Electrical parts suitable for aluminum and aluminum alloy to produce gold film, excellent corrosion resistance, and paint has good adhesion. First, the simple characteristics 1. operation, long life, low cost. 2. strong adsorption, can be used for the bottom before spraying. 3. The combination of strong, improve the bonding strength of the coating. The film has conductivity. 5. oxide film uniformity, strong corrosion resistance, salt spray test up to 100 hours. It can replace general-purpose sulfuric acid anodizing film. Second, the bath composition DCHZ-405A (liquid) 50ml / L DCHZ-405B (liquid) 50ml / L Third, the process parameters temperature 15-30 ℃ PH value 1.5-2.2 3-5 minutes four times, the process degreasing → washing (twice) → base erosion film → washing (twice) → DCHZ-405 → water (three times) Note: The drying temperature ≤60 ℃ Fifth, Bath maintenance: by consumption added. Six consumption: 3-5kg DCHZ-405A / tonne of aluminum, 3-5kg DCHZ-405B / tonne aluminum.
