Abstract：

TiB2-316L　stainless　steel　matrix　composite　powders　contained　10mass%　and　40mass%　TiB2　were　prepared　by　high　energy　ball　milling　and　spray-drying　processes　respectively.　Atmospheric　plasma　spraying　deposited　corresponding　coatings　and　316　L　stainless　steel　coating.　High　velocity　block-on-ring　wear　tester　was　used　to　test　wear　resistance　of　as-sprayed　coatings.　X-ray　diffraction　analyzed　the　constitution　of　as-sprayed　coatings.　Scanning　electron　microscope　was　employed　to　character　as-sprayed　coatings,　feedstocks　and　the　worn　surface　morphology.　Results　show　that　wear　resistance　of　as-sprayed　TiB2-316L　stainless　steel　matrix　composite　coatings　is　prior　to　316L　stainless　steel　coating.　TiB2　particles　act　as　reinforcement　component　in　the　coating　and　oxides　from　tribo-oxidation　of　TiB2　in　the　tribo　contact,　which　possessed　self-lubricating　function,　can　reduce　mass　loss　of　the　coatings　during　sliding　wear.
