pretreatment before plating is to obtain a clean and fresh metal surface in preparation for the final high-quality plating. To degrease, to rust, to dust and other work. The steps are as follows:
the first step is to make the surface roughness reach a certain requirement, and
the second step can be degreased and degreased by surface polishing, polishing and other technological methods, which can be realized by solvent dissolution, chemical and electrochemical methods;
The third step of rust removal can be carried out by mechanical, pickling and electrochemical methods.
The fourth step of activation treatment is generally carried out by etching in weak acid for a certain time.
