Notes:
The mainly process of electrochemical graining on 6063 aluminum alloy included grainingat alternating current, anodizing and chemical coloring. The graining used NaBO2- H3BO3 system asfilm-forming solution, proper AC current density, treating time, temperature , adding agents andsolution concentration were ascertained through operating orthogonal experiment, the grain ofappropriate density and width could be obtained, the grained surface of aluminum alloy presentedintergranular corrosion in the graining zone, the appearance was improved after anodizing, enoughthick anodizing film could make intergranular corrosion eliminated. Cyclic voltammetry experimentwas used to preliminarily explaine the grain process, the main cause of graining zone formation washydrogen evolution
