Abstract：

Two　different　types　of　agglomerate　and　angular　WC/Ni　matrix　composite　coatings　were　deposited　by　laser　cladding.　The　high　temperature　wear　resistance　of　these　composite　coatings　was　tested　with　a　ring-on-disc　MMG-10　apparatus.　The　morphologies　of　the　worn　surfaces　were　observed　using　a　scanning　electron　microscopy　(SEM)　equipped　with　an　energy　dispersive　spectroscopy　(EDS)　for　elemental　composition.　The　results　show　that　the　high　temperature　wear　resistance　of　the　laser　clad　WC/Ni-based　composite　coatings　is　improved　significantly　with　WC　mass　fraction　increasing.　The　60%　agglomerate　WC/Ni　composite　coating　has　optimal　high　temperature　wear　resistance.　High　temperature　wear　mechanism　of　60%　WC/Ni　composite　coating　is　from　abrasive　wear　of　low　temperature　into　composite　function　of　the　oxidation　wear　and　abrasive　wear.　©　2016,　Journal　of　Materials　Engineering.　All　right　reserved.
