Ti(C,　N)-TiB2　composite　cermets　with　different　binders　(high　entropy　alloy　(HEA)　or　Ni-Co)　were　fabricated　by　mechanical　alloying　and　vacuum　hot-pressing　sintering.　The　wear　resistance　of　the　two　composite　cermets　at　elevated　temperatures　was　studied.　Wear　mechanism　was　characterized　by　a　combination　of　scanning　electron　microscopy　and　energy　dispersive　spectroscopy.　The　experimental　results　indicated　that　HEA　binder　composite　cermets　possessed　excellent　wear　resistance　comparing　with　Ni-Co　binder　composite　cermets.　At　lower　temperatures,　no　obvious　difference　was　observed　in　the　worn　surfaces　of　two　cermets.　Abrasive　wear　mechanism　was　dominant　wear　mechanism.　At　greater　than　600　°C,　oxidative　wear　and　adhesive　wear　were　found　to　be　dominant　wear　mechanism.　The　wear　rate　of　the　HEA　binder　composite　cermets　was　11.8　%,　17　%,　39.25　%,　and　46.7　%　lower　than　that　of　the　Ni-Co　binder　composite　cermets　at　200　,　400　,　600　,　and　800　,　respectively.　The　enhanced　wear　performance　of　Ti(C,　N)-TiB2-HEA　composite　cermets　is　attributed　to　relatively　high　hardness　and　toughness,　as　well　as　excellent　high-temperature　softening　resistance　and　oxidation　resistance　of　HEA.　©　2021
