摘　　要：在Ti基底上激光熔覆Zr_(65)Al_(7.5)Ni_(10)Cu_(17.5)合金粉末,得到含非晶、纳米晶和金属间化合物复合组织涂层。结构分析和微观表征表明,晶体相为简单正方的Al_2Zr_3及Zr_2Cu、Zr_2Ni。熔覆层与基本结合区为典型外延生长柱状晶,最终凝固形成(Ti/Zr)固溶体。Zr65A17. 5NilOCul7. 5 alloy powers have been cladded on Ti substrate. The coatings constitute of amorphous, intermetallic phases and nanocrystalline. Structure analysis andMicrostructure token show that the crystalline were Zr2Cu,Zr2Ni and A12Zr3. The bonding zone between substrate and coating is composed of columnar crystalline of Ti and a -type solid solution(Ti/Zr)
