摘要
Abstract
The service life of resistance spot welding electrode is short when welding galvanized steel.For extending the life of resistance spot welding electrode,particle-reinforced copper matrix composites electrode materials,especially Al2O3/Cu composites electrode materials have got people's attention.ln ordeT to obtain the best process parameters,in this paper,Al2O3/Cu composite electrode materials was prepared by powder metallurgy.Taking density,Vickers hardness,conductivity and microstructure as the evaluation contents,research on mechanical properties and microstructure of Al2O3/Cu composite electrode materials influenced by pressing force and sintering temperature are done by changing the process parameters.The result was as followed:The best process parameters are obtained that the pressing force is 100 kN and sintering temperature is 940℃.关键词
