[0018] see figure 1 As shown, the present invention relates to a pretreatment process for die-casting aluminum alloy electroplating, comprising the following steps:
[0019] S1, degreasing treatment, use a degreasing agent to perform degreasing treatment on the die-casting aluminum alloy parts, remove the oil stains on the surface, and then perform water washing treatment;
[0020] S2. Alkali etching treatment, the die-casting aluminum alloy parts are placed in an alkaline solution for alkaline etching treatment to remove the oxide film and metal ions on the surface, and then washed with water;
[0021] S3, descaling treatment, using a descaling agent to perform descaling treatment on the die-casting aluminum alloy parts, remove the residue on the surface after alkali corrosion, and then perform water washing treatment;
[0022] S4. Activation treatment. Place the die-casting metal alloy parts in an activation solution with a pH value of 5.5-6.6 at room temperature for 10-30 ...
