摘　　要：研究了提高6063铝合金表面耐蚀性能的途径,并从理论上分析了改善耐蚀性能的作用机理。结果表明:合理调整合金的化学成分有利于提高材料的耐蚀性能,Mg,Si元素的质量比值在1.55附近时性能较佳;对铸锭进行必要的均匀化处理有助于型材耐蚀性能的提高,均匀化后铸锭适宜采取快速冷却;挤压工艺对材料的腐蚀性能有重要影响,型材的出口温度在510℃左右时具有较好的耐蚀性能。The approach to improving surface corrosion resistance of 6063 aluminum alloy was studied,and the mechanism of surface corrosion resistance was discussed in theory.The results indicate that reasonable chemical composition is of advantage to corrosion resistance,its property is better as Mg,Si mass ratio at about 1.55.The necessary homogenizing treatment of cast ingot subserves corrosion resistance of aluminum extrusion,and the cast ingot should be cooled quickly after heat treatment.Significant effect of extrusion technology on erosive property is observed for aluminum alloy,aluminum extrusion has good corrosion resistance when outlet temperature is at about 510℃.
