摘要：

Fe-Cr-B-C-Nb　cladding　layer　containing　submicron　NbC　were　prepared　by　PTA　on　Q235　steel,　a　series　of　alloys　containing　superfine　NbC,　eutectic　boride,　NbC　+　eutectic　boride,　NbC+primary　Fe2B　hardphase　were　designed　respectively　to　study　the　effect　of　hardphase　of　different　size　on　microstructure　and　properties　of　Fe-Cr-B-C-Nb　cladding　layer,　and　compared　with　the　Fe-Cr-C　hardfacing　alloy　in　market.　The　results　show　that　the　fine　hardphase　can　conduce　to　improve　the　impact　resistance　and　the　wear　resistance　of　the　alloy　containing　submicron　NbC　and　eutectic　boride　is　4　times　more　than　that　of　Fe-Cr-C,　and　the　impact　resistance　is　better　than　that　of　Fe-Cr-C.　©,　2015,　Beijing　Institute　of　Aeronautical　Materials　(BIAM).　All　right　reserved.
