| Abstract: | Through the tests of high temperature hardness and wear resistance,the properties of iron-base Cr-Mo-W-V-Nb system plasma arc surfacing alloy high temperature abrasive wear resistance are investigated.This alloy can replace the expensive Nichel-base and Cobalt-base plasma arc surfacing alloys.The wear-resistance of surfacing alloys and behavior of hard phase in high temperature are investigated systematically,i.e.the effect of hard phases,such as Cr7C3 ,Cr3C ,WC,W2C,NbC and VC,on microsturcture,hadness and wearability of the surfacing layer has been studied.The results prove that the different shape,amount and size of the hard phase have different effect on the wear-resisting of the surfacing layer.\= |
