摘　　要：[目的]研究不同材质游离微珠对摩擦辅助电铸铜层力学性能的影响。[方法]分别使用直径为0.8~1.2mm的氧化铝陶瓷微珠和氧化锆陶瓷微珠作为摩擦辅助介质进行电铸铜,对比所得Cu电铸层的表面微观形貌、截面金相组织和力学性能。[结果]氧化锆陶瓷微珠对Cu电铸层表面具有更强的磨削作用,能有效减少表面毛刺和凸起,以及起到细化晶粒的作用。使用氧化锆陶瓷微珠制备的Cu电铸层的显微硬度为147.2 HV,抗拉强度为308.3 MPa,延伸率为19.8%,分别比采用氧化铝陶瓷微珠摩擦辅助时所得的Cu电铸层高了约10.3%、5.7%和2.3%。[结论]选择合适的游离微珠作为摩擦介质可以改善电铸层的表面品质,提升其力学性能。[Introduction]The effects of free microbeads made of different materials on mechanical properties of the copper coating prepared by friction-assisted electroforming need to be studied.[Method]Friction-assisted electroforming of copper was conducted using alumina ceramic microbeads or zirconia ceramic microbeads with a diameter ranging from 0.8 to 1.2 mm as abrasives.The surface micromorphology,cross-sectional metallographic structure,and mechanical properties of the electroformed Cu coatings were compared.[Result]The zirconia ceramic microbeads exhibited a stronger grinding effect on the surface of Cu coating,effectively reducing the number of surface burrs and protrusions and refining the grain size.The Cu coating electroformed under the friction of zirconia ceramic microbeads had a microhardness of 147.2 HV,a tensile strength of 308.3 MPa,and an elongation rate of 19.8%,which were approximately 10.3%,5.7%,and 2.3% higher respectively than those of the Cu coating electroformed with alumina ceramic microbeads as abrasives.[Conclusion]Selection of suitable free beads as abrasives can improve the surface quality and mechanical properties of copper coating.
