The　influence　of　vanadium　content　on　high-temperature　mechanical　properties　of　hardfacing　deposited　metal　was　investigated,　on　the　basis　of　keeping　other　compositions　of　Cr5　Series　hardfacing　alloy　system　unchanged.　The　results　show　that　vanadium　has　different　existing　statuses　in　the　hardfacing　deposited　metal,　and　different　influence　laws　on　room-temperature　hardness　and　micro-hardness.　At　600　degrees　C,　with　the　increasing　of　vanadium　content,　wear　resistance　is　improved　firstly,　and　then　started　to　decreased　when　the　maximum　value　reschis　to　at　0.30%,　until　to　the　lowest　wear　resistance　at　0.60%.　When　the　vanadium　content　is　within　0　similar　to　0.60%,　with　the　increasing　of　vanadium　content,　the　friction　coefficient　decreases　gradually;　when　it　exceeds　0.60%,　with　the　increasing　of　vanadium　content,　the　coefficient　increases.　High-temperature　wear　depends　on　the　toughness,　strength,　microstructure　and　oxidation　resistance　of　hardfacing　material　greatly,　and　is　influenced　by　many　factors　comprehensively.
