摘　　要：对6063-T6、6082-T6和6005A-T6铝合金分别进行阳极氧化、阴极电泳和粉末静电喷涂三种表面处理,通过对铝合金基体及三种表面处理后膜层表面进行不同时间的AASS试验。结果表明,经过表面处理前,6063铝合金的耐腐蚀性能好于6082和6005A铝合金;经过不同表面处理后,三种铝合金表面的耐腐蚀性能均有提高,腐蚀性能提高的程度由强到弱为,阴极电泳>粉末静电喷涂>阳极氧化。In this paper,the aluminum alloy 6063-T6,6082-T6 and 6005A-T6 are treated by anodic oxidation,cathodic electrophoresis and powder electrostatic spraying respectively.AASS tests are carried out on the aluminum alloy substrate and the film surface after the three surface treatments.The results show that the corrosion resistance of 6063 aluminum alloy is better than that of 6082 and 6005A aluminum alloy before surface treatment.After different surface treatment,the corrosion resistance of three kinds of aluminum alloy surface is improved.The degree of corrosion resistance improvement is from strong to weak,cathode electrophoresis>powder electrostatic spraying>anodic oxidation.
