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　degrees　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　degrees　C,　400　degrees　C,　600.,　and　800　degrees　C,　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.
