摘要
搅拌摩擦焊被广泛应用于航空航天等重要工业领域的高强铝合金结构件的连接,由于高强铝合金接头的抗腐蚀性能较差,限制了其进一步的应用,实际应用中必须对接头进行腐蚀防护。文中详细综述了目前高强铝合金搅拌摩擦焊接头的四种腐蚀防护方法:降低热量输入、焊后热处理、表面改性和喷涂涂层,指出了高强铝合金搅拌摩擦焊接头腐蚀防护今后的研究方向。
Friction stir welding （FSW） has been aluminum alloys can be well joined. However, the widely used in many industries, with which high-strength corrosion resistance of FSW high-strength AI alloy joints is relatively poor, which limits their industrial applications. The joints shall be protected against corrosion. In this review, therefore, the current status and development of corrosion protection for FSW high-strength A1 alloy joints are presented. Particular emphasis has been given to different protection methods： lowering heat input, post-weld heat treatment, surface modification and spray coatings. Finally, opportunities are identified for further research and development in corrosion protection of FSW high-strength AI alloy joints.
