摘　　要：为了改善Tc4钛合金板材制造零部件的表面质量,降低其表面粗糙度,提出了一种高效率的电解-旋转超声磁粒复合研磨抛光方法。设计了电解-旋转超声磁粒复合研磨抛光的实验装置,对不同加工工艺下所得的合金表面的表面粗糙度、表面残余应力进行分析。结果表明,经过20min加工后,复合研磨使表面粗糙度由1.92μm降至0.09μm,改善了表面质量。表面残余应力由+186MPa转变为-51MPa,即由拉应力变为压应力,获得更好的表面应力状态。In order to improve the surface quality and reduce the surface roughness of parts made of Tc4 titanium alloy sheet,an electrolysis-rotating ultrasonic magnetic particle composite grinding method was proposed. The experimental device for the method was designed,and the surface roughness and residual stress of the worked alloy with the device under different processing technic were analyzed. The results showed that the surface roughness reduced from 1.92 μm to 0.09 μm by composite grinding after 20 minutes processing time,which improved the surface quality. The residual stress on the surface was changed from +186 MPa to -51 MPa,it meant the form of stress was changed from tensile stress to compressive stress,which could provide a better state of surface stress.
