摘　　要：铝合金壳体和零部件的自身优点是比重小、可加工性好、力学性能优异、导电导热能力强,但其自身形成的氧化膜很难抵抗应用环境的腐蚀,必须通过合理的表面处理方法来提高其耐蚀性能。因此,研究铝合金的防腐性能具有重要意思,文章将介绍几种提高铝合金耐蚀性的表面处理工艺。The advantage of aluminum alloy shell and its parts is small proportion,good workability,mechanical perfor-mance is excellent,thermally conductive capability is strong,but its own form of oxide film is hard to resist corrosion environment,must through the reasonable surface treatment methods to improve its corrosion resistance.So it is of great significance to study the anticorrosion properties of aluminum alloy.This paper introduces several surface treatment technologies to improve the corrosion resistance of aluminum alloys.
