摘　　要：在铝材基体上，综合应用等离子喷涂和电弧喷涂等热喷涂方法，喷涂钽、镝、铅等材料，制备具有辐射屏蔽效应的多层复合涂层。用光学显微镜和ＳＥＭ对复合涂层的组织结构进行了观察分析，定量分析了涂层的化学成分，测量了喷涂样品的平面度误差和涂层重量。结果表明，涂层之间结合紧密，组织均匀致密，孔隙率低，满足了辐射屏蔽要求，达到了预期效果。The tantalum, dysrosium and lead composite coating on aluminium substrate was prepared by thermal and plasma spraying, The composition, structure, density and flatness of the coating were determined by OM, SEM and EDAX. It was shown that the coating was homogeneous and compact in structure. It could meet the requirements of radiation screening.
