Traditionally,　wear-resistant　components　are　manufactured　by　cladding　hard　facing　material　on　the　base　metal.　This　production　process　is　typically　complicated,　expensive,　and　time-consuming.　This　study　proposes　a　method　of　fabricating　components　with　high　wear　resistance　requirements　utilizing　cold　metal　transfer　based　wire　and　arc　additive　manufacturing　with　hard　facing　welding　wire　as　the　consumable　material.　Thin-walled　and　block　components　were　manufactured　by　depositing　a　combination　of　a　low　alloy　steel,　ER80S-G,　and　a　hard　facing　material,　MF6-55GP.　Microstructure　characterization　and　mechanical　properties　(hardness,　tensile　and　Block-on-Ring　wear　test)　were　performed.　The　results　revealed　that　the　ER80S-G/MF6-55GP　bimetal　components　were　able　to　be　fused　with　no　detectable　defects　near　the　border.　As　the　deposited　height　was　increased,　the　residual　stress　also　increased;　this　internal　residual　stress　combined　with　the　external　tensile　load　lead　to　a　very　low　tensile　strength　of　447.79　24.32　MPa　of　the　ER80S-G/MF6-55GP/ER80S-G　sandwich　structure.　The　microstructures,　constituent　phases,　and　hardness　distributions　differ　greatly　among　the　layers　due　to　their　different　thermal　histories.　The　wear　weight　loss　varies　as　the　load　condition　changes　for　both　the　MF6-55G　and　Cr12MoV　steels.　Compared　to　Cr12MoV,　MF6-55GP　weld　metal　exhibits　better　wear　resistance　at　higher　loads　in　dry　sliding　wear　tests.
