摘要
铝合金是工业上十分重要的有色金属材料,但由于其表面硬度低、耐磨性差而制约了其进一步应用。在铝合金表面进行激光熔覆,可以形成与基体呈冶金结合的涂层,显著改善铝合金表面性能,同时该技术也可对损伤铝合金零件进行修复,展现出极高的应用价值。随着科技的不断发展,铝合金表面激光熔覆技术已经成为国内外研究的一大热点,相关研究工作不断增加。然而,鲜有文献对该技术的发展现状进行综述。介绍了铝合金激光熔覆的基础知识,重点阐述了当前铝合金表面激光熔覆的材料体系,包括铝合金、镍基合金、陶瓷、高熵合金等,并简要介绍了该技术领域的新研究方法和工艺,最后展望了铝合金激光熔覆未来的发展。本文可为铝合金表面激光熔覆技术的研究人员提供参考。
Aluminum alloy is one of the most important nonferrous metal in the application of industry while the surface performance like hardness and wear-resistance are usually poor,restricting the further application of aluminum alloy.Laser cladding on the surface of aluminum alloy can form a metallurgical bonding coatings with substrate,which can effectively improve the surface properties of aluminum alloy.Laser cladding can also repair aluminum alloy parts,showing high application value.The laser cladding on the surface of aluminum alloy has become a hot topic at home and abroad and the related research works are increasing day by day with the continuous development of science and technology.However,there is few literature to summarize the development status of laser cladding.This paper introduces the basic knowledge of aluminum alloy laser cladding,and focuses on the current material system of laser cladding on the surface of aluminum alloy,including aluminum alloy,nickel base alloy,ceramics,high entropy alloy,etc.,and briefly introduces the newly research methods and processes in this field.Finally,the development prospect of aluminum alloy laser cladding is prospected.This paper can provide reference for the researchers of laser cladding technology on the surface of aluminum alloy.
