摘　　要：综述了稀土元素掺杂、表面涂层和晶界工程三种提高铝铜合金耐蚀性方法的研究现状,并对铝铜合金晶间腐蚀未来的研究方向进行了展望。通过晶界工程提高近奇异晶界的比例,从而改善铝铜合金的抗晶界腐蚀性能,对铝铜合金的有效防护提供了参考意义。The research status of three treatment methods for improving the corrosion resistance of Al-Cu alloy,including rare earth element doping,surface coating and grain boundary engineering is reviewed,and the future research direction of Al-Cu alloy intergranular corrosion is prospected.Through grain boundary engineering,the proportion of near singular grain boundaries is increased,so as to improve the grain boundary corrosion resistance of Al-Cu alloy,which provides a reference for the effective protection of Al-Cu alloy.
