The Investigation of Material Transfer Characteristics and Surface Morphology of Ptlr Contact Materials

摘要：

　　Material transfer characteristics and surface morphology of contact material reflects their electrical erosion performance.In this paper,by using a JF04C contact material testing machine,the characteristics of electrical erosion of PtIr contact materials are acquired under low voltage,resistive load and small current,By means of an electronic balance and SEM,the material transfer values of the PtIr contact materials and the characteristics of contact material surface profile are obtained and analyzed.The results show that PtIr alloy contact materials mainly transfer from cathode to anode and its breaking arcs are metallic phase.
