In　order　to　achieve　the　demand　for　improving　the　wear　resistance　of　titanium　alloy　surfaces,　a　combination　of　magnetron　sputtering　(PVD),　chemical　vapor　deposition　(CVD)　and　thermal　vulcanization　methods　is　used　to　prepare　highly　wear-resistant　WS2/W　Composite　coating　on　the　surface　of　TC4　titanium　alloy.　Scanning　electron　microscope　(SEM),　X-ray　diffractometer　(XRD)　and　X-ray　energy　dispersive　spectrometer　(EDS)　were　used　to　characterize　the　micro-morphology,　microstructure　and　chemical　composition　of　the　composite　coating.　The　micro-hardness　and　wear　resistance　of　the　composite　coating　were　tested.　The　results　show　that　the　thickness　of　each　layer　of　the　WS2/W　composite　coating　prepared　by　the　experiment　is　about　16µm　and　60µm　respectively,　the　coating　structure　is　dense,　and　the　interface　between　the　layers　is　obvious.　The　average　micro-hardness　of　WS2　layer　and　W　layer　are　110.4HV　and　740.1HV　respectively.　The　surface　friction　factor　of　WS2/W　composite　coating　is　0.15,　which　is　about　18%　of　the　matrix　(0.85).　The　wear　rate　is　1.184　×　10-6mm3•mm-1,　which　is　about　45%　of　the　substrate　(1.628　×　10-6mm3•mm-1),　which　has　better　wear　resistance　and　anti-friction　characteristics.　©　Published　under　licence　by　IOP　Publishing　Ltd.
