  • 摘要: 为了提高铝合金表面的力学和耐腐蚀性能,利用激光沉积技术在铝合金表面制备了AlCrFeCoNiCu高熵合金涂层。使用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、能谱分析仪(EDS)、显微硬度计和电化学工作站,研究了涂层的相结构、微观组织、元素分布、硬度及耐腐蚀性能。结果表明,涂层与基材结合良好,基材中Al元素在熔池搅拌作用下上浮,使沉积层呈FCC相和BCC相;显微组织为典型的枝晶结构,Cu元素在枝晶间富集;涂层平均显微硬度为528HV0.2,约是基材的5倍;AlCrFeCoNiCu涂层在3.5% NaCl溶液中的腐蚀特征为点蚀和晶间腐蚀,耐腐蚀性优于基材。激光沉积制备的AlCrFeCoNiCu高熵合金可以改善铝合金表面性能。
