摘　　要：应用惯性径向摩擦焊工艺研究了T3、H96、B5三种铜合金与35CrMnSi的摩擦焊接性,确定三种材料的焊接性能否满足使用要求。通过强度检测、金相、硬度测试表明:三种铜合金与35CrMnSi均能形成良好的摩擦焊接头;接头剪切强度与铜合金等强,不会产生焊接气孔等熔化焊工艺存在的焊接缺陷。研究也表明,因为熔点与导热的影响,B5+35CrMnSi钢侧的热影响区较宽。三种材料与35CrMnSi的径向摩擦焊接性能满足使用要求。In order to determine whether the welding properties can meet the operating requirements of the products, the welding properties of three kinds of aldary （T3, BS, H96） with 35CrMnSi by the use of inertial radial friction welding are studied. Experiments have been done such as the microstructure analysis of the welding joint, shear strength and Vickers-hardness test. The results show that T3 copper, B5 cupronickel and H96 brassiness welded with steel possesse high properties. The shear strength of joints reaches more than 200 MPa, and there is no hole flaw which can be often found in fusion welding. The results also indicate that the microstructures of HAZ on BS＋35CrMnSi steel side are wider because of the melting point and conduction. The welding properties can satisfy the operating requirements of the products.
