摘要：

The　composite　powder　of　Mo-(NiCr-Cr3C2)　was　mechanically　blended　and　deposited　using　atmospheric　plasma　spraying.　The　mechanical　property　and　tribological　performance　of　the　prepared　coating　were　tested.　The　results　show　that　the　porosity　and　the　microhardness　of　the　composite　coating　are　inversely　proportional　to　the　Mo　content.　The　coating　with　the　Mo　addition　of　20%(mass　fraction)　presents　better　performance　in　the　frictional　test.　All　the　composite　coatings　mainly　endures　adhesive　wear　and　abrasive　wear.　The　coating　containing　large　portion　of　NiCr-Cr3C2　is　prone　to　flake　during　the　wear.　The　wear　resistance　of　the　coating　shows　a　good　accordance　with　the　index　of　H/E　of　the　coating.
