Argon-arc Welding of Cu/Ti3AlC2 Cermet

摘要：

　　Joining of Cu/Ti3AlC2 cermet by an argon-arc welding technique without filler was firstly investigated.The results show that the Cu/Ti3AlC2 cermet can be joined firmly.The joining strength at room temperature was measured to be 851 MPa after optimization of the welding parameters with 2.6 A/mm2 for arc current density,5 s for arc time,10.8 kPa for applied pressure and 12 V for arc voltage.The microstructure in welded zone shows that fine TiCx particles uniformly dispersed in a network structure of Cu-Al alloys.This feature endows the Cu/Ti3AlC2 cermet with the high joining strength.
