Aluminum and aluminum alloy electroplating operation precautions
1. Aluminum alloy should be used as hanger for electroplating of aluminum parts;
2. The various processes of aluminum and aluminum alloys after etching must be carried out quickly, and the interval between processes is as short as possible to avoid re-oxidation;
3. The second galvanizing time should not be too long to avoid excessive corrosion;
4. Washing must be clean;
5. During the electroplating process, it is necessary to prevent power failure in the middle.
