摘　　要：在喷射电沉积过程中加入硬质颗粒摩擦辅助装置,快速成型了金属铜零件;采用光学显微镜观察了铜零件的表面形貌,采用显微硬度仪对其硬度进行了测试,采用万能材料试验机对其抗压和抗拉强度进行了测试。结果表明:采用该方法可快速成型形状良好、表面平整、晶粒细小的零件;其硬度分布均匀,平均为353.28 HV,抗压性能较好,强度为675 MPa;x方向抗拉、屈服强度分别为390,372 MPa;z向拉伸强度虽有所降低,但仍优于工业用冷轧铜的。Adding hard particles friction device in jet electrodeposition process, metal copper parts were obtained by rapid prototyping. The surface morphology was observed by optical microscopy. Its hardness was tested by micro hardness tester. Its compressive strength and tensile strength were measured by universal testing machine. The results show that the parts obtained by the method had good shape, smooth surface and small grains. The hardness distribution was uniform and the average value was 353.28 HV. The compressive strength was 675 MPa. Tensile strength and yield strength in x direction were 390 and 372 MPa, while those in z direction were reduced, but still better than cold-rolled copper for industry.
