NbC　powder　was　added　in　coating　of　the　Fe-Cr-C　hardfacing　electrodes.　The　effect　of　NbC　on　the　microstructure　and　properties　of　deposited　metal　was　studied.　The　results　show　that　the　NbC　strengthened　Fe-Cr-C　hardfacing　alloy　has　higher　hardness　and　better　abrasion　wear-resisting　property.　The　hardness　of　NbC　strengthened　Fe-Cr-C　hardfacing　alloy　reach　to　61.7　HRC,　9.5%　more　than　Fe-Cr-C　hardfacing　alloy.　And　the　relative　abrasion　wear-resisting　property　of　NbC　strengthened　Fe-Cr-C　hardfacing　alloy　increased　60%　comparing　to　the　Fe-Cr-C　hard-facing　alloy.　The　cross　shape　of　NbC　hard　phase　in　Fe-Cr-C-NbC　alloy　is　erose,　showing　as　rhombic　or　polygonal　shape　distributed　between　the　M7C3　or　embed　in　the　M7C3.　The　distribution　of　NbC　phase　is　not　uniform,　and　it　congregates　in　local　regions.　The　eutec-tic　carbides　in　the　Fe-Cr-C-NbC　alloy　show　coarse　structure　compared　to　the　Fe-Cr-C　hardfacing　alloy,　and　the　space　between　them　is　much　great.
