高体积分数SiCp/Al复合材料电解-机械组合低磨损加工方法研究
Study on Low Wear Machining Method of High Volume Fraction SiCp/Al Composite Materials by ECM-mechanical Combined Machining Processes Method
摘要
Abstract
To improve the problems of tool wear,poor surface quality and low machining efficien-cy of aluminum-based silicon carbide(SiCp/Al)composites with high volume fraction under conven-tional machining,an ECM-mechanical combined machining method was proposed,and the ECM-mechanical combined machining experiments of 60％volume fraction SiCp/Al composites were carried out.The results show that SiC particles are exposed on the surfaces with the removal of aluminum matrix.There is a certain depth of transition zone between the surface of the workpiece and the matrix after ECM,the aluminum matrix in the transition zone is locally removed,and the binding force of SiC particles is reduced.When the diamond grinding rod is used for machining the transition zone,the aluminum matrix adhesion phenomenon is not observed,the diamond grinding rod has almost no wear,and the surface damages are obviously reduced.The machinability of high volume fraction SiCp/Al composites may be improved by ECM-mechanical machining processes.关键词
