依托电沉积技术为主要工艺平台,辅助超声振荡搅拌措施,制备Cu-SiC复合镀层,并研究复合镀层的表面状况、显微结构、硬度及耐腐蚀性.结果表明:与常规Cu-SiC复合镀层相比,辅助超声振荡电沉积的Cu-SiC镀层表面粗糙度降低,择优取向面从(220)面转变为(111)面,硬度提高且耐腐蚀性增强;但对超声复合镀层而言,提高阴极电流密度可增大其表面粗糙度,弱化组织结构,从而降低硬度并削弱耐腐蚀性.
The Cu?SiC composite coating was prepared by electrodeposition assisting with ultrasound oscillation,and its surface quality,microstructure,hardness and corrosion resistance were studied. The results show that in comparison with the conventional Cu?SiC coating,the one obtained under ultrasound oscillation conditions presents better topography,different preferred orientation plane which transforms from(220)to(111),higher hardness and better corrosion resistance. However, the surface roughness is increased and the microstructure is loosened with the increase of cathode current density,which lowers hardness and weakens corrosion resistance.
