As　a　typical　wear-resistant　material,　TiC　particle-reinforced　AlCoCrFeNi　composite　coatings　have　great　advan-tages.　In　this　work,　the　Mo　was　added　to　AlCoCrFeNi-TiC　coatings　to　further　improve　the　wear　resistance,　which　were　fabricated　as　AlCoCrFeNiMox-TiC　(x:　molar　ratio;　x　=　0,　0.2,　0.5,　0.8)　composite　coatings　by　laser　cladding.　The　microstructure　evolution,　hardness,　and　wear　resistance　were　investigated　in　detail.　The　results　show　that　a　ring　of　(Ti,　Mo)C　phase　is　formed　in　the　outer　layer　of　TiC　particles　due　to　the　substitution　of　Mo　atoms.　Based　on　the　first-principles　calculations,　the　lattice　constant　of　(Ti,　Mo)C　phase　is　4.328　angstrom,　slightly　smaller　than　that　of　TiC.　More　importantly,　Mo　can　significantly　reduce　the　interface　energy　from　0.27　J　center　dot　m(-2)　to　-0.18　J　center　dot　m(-2),　thus　improving　the　interface　stability.　The　coating　matrix　(CM)　exhibits　a　spinodal　structure　of　B2　+　sigma　phase,　caused　by　the　generation　of　sigma　phase.　The　sigma　phase　has　a　calculated　hardness　of　about　15.3　GPa,　which　is　undoubtedly　conducive　to　wear　resistance　of　the　CM.　With　the　addition　of　Mo,　the　hardness　of　composite　coating　increases　from　611.9　HV0.3　to　822.6　HV0.3.　All　the　coatings　present　high　wear　resistance,　as　evidenced　by　the　abrasive　wear　mechanisms.
