In　order　to　prepare　two　kinds　of　composite　coatings　for　comparison,　TiB2　and　Ni+TiB2　were,　respectively,　used　as　cladding　materials,　and　the　composite　coatings　were　prepared　by　laser　in-situ　cladding　technique　on　the　surface　of　titanium　alloy.　The　synthesized　titanium-based　composite　coatings　were　studied　by　XRD,　SEM,　EPMA　and　friction　and　wear　instruments.　The　results　show　that　TiB2　particle　and　TiB　short　fiber　reinforced　titanium-based　composite　coating　can　be　obtained　when　TiB2　is　used　as　the　cladding　material.　When　Ni+TiB2　is　used　as　the　cladding　material,　the　NiTi　alloy　can　be　formed　to　be　filled　around　the　TiB2　particles　and　the　TiB　short　fibers,　but　the　size　of　the　TiB2　particles　and　the　length　of　the　TiB　short　fibers　are　all　reduced.　Through　the　fretting　wear　test,　it　is　found　that　the　composite　reinforcement　of　NiTi　alloy　and　TiB2　particles　and　TiB　short　fiber　can　not　effectively　resist　the　fretting　wear　performance.　There　are　three　reasons　for　this:　the　temperature　of　the　friction　contact　zone　exceeds　the　temperature　of　the　NiTi　superelastic　deformation,　the　crack　propagation　cannot　be　deflected　by　the　introduction　of　NiTi,　the　hardness　of　the　NiTi　alloy　is　low.　Finally,　the　difference　between　the　anti-friction　wear　and　dry　sliding　wear　of　the　composite　coating　was　discussed.　©　2020,　Science　Press.　All　right　reserved.
