摘要
综述了铝合金搅拌摩擦焊接头腐蚀性能的研究进展,总结和评价了接头耐蚀性的常用研究方法。介绍了铝合金搅拌摩擦焊接头应力腐蚀开裂敏感性和常规试验方法,并提出要对搅拌摩擦焊接头腐蚀寿命进行预估,最后列举了改善接头耐蚀性的处理方法。
The corrosion properties of aluminium alloy friction stir welds were reviewed,and the research methods about corrosion resistance of the joints were summarized and evaluated.The stress corrosion cracking(SCC) sensitivity of aluminium alloy friction stir welds and some conventional SCC test methods were introduced.Meanwhile,the method to predict the corrosion life of aluminium alloy friction stir welds was proposed.Finally methods to improve the corrosion resistance of joints were listed.
