Two　type　of　ceramic　composite　coatings　of　Fe-Cr-B　alloy　reinforced　with　cobalt-coated　tungsten　carbide　(WC-Co)　particles　or　nickel-coated　tungsten　carbide　(WC-Ni)　particles　were　deposited　on　a　mild　steel　substrate　by　are　spraying,　respectively.　The　microstructure　of　the　coating　was　investigated　by　optical　microscopy.　X-ray　diffraction　analysis　was　used　to　study　the　phase　composition　in　the　coating.　The　microhardness　of　the　coating　was　determined.　The　wear　behavior　of　the　coating　was　evaluated.　The　results　showed　that　the　WC-Co/FeCrB　coating　has　the　excellent　abrasive　wear　resistance　which　is　about　11　times　higher　than　that　of　Q235　mild　steel.　The　main　wear　mechanism　of　both　coatings　was　silica　scratching　and　micro-cutting　of　the　matrix　and　the　resultant　pulling　out　of　WC　particles.
