High-entropy　alloy　(HEA)　coatings　of　AlCoCrFeNi　are　being　investigated　as　potential　wear-resistance　materials　due　to　their　excellent　hardness　and　wear　resistance.　In　this　work,　AlCoCrFeNi-based　coatings　were　reinforced　by　in-situ　TiC　particles　via　laser　cladding.　The　microstructure　and　wear　resistance　were　investigated　using　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　and　wear　resistance　tests.　In　addition,　the　hardness　of　oxidation　TiC　particles　was　analyzed　by　first　principles　calculations.　The　results　show　that　the　dominant　phase　of　AlCoCrFeNi-based　coatings　is　BCC　phase.　In-situ　TiC　particles　present　a　flower-shaped　morphology　with　Al2O3　core.　Based　on　the　calculated　hardness,　the　hardness　of　TiC　decreases　with　the　increase　of　oxygen　atoms　in　TiC.　The　hardness　and　wear　resistance　are　improved　considerably　with　the　generation　of　the　in-situ　TiC　particles.　The　AlCoCrFeNi-20%　TiC　coating　exhibits　the　best　wear　resistance　with　an　average　hardness　of　684.4　HV0.3,　and　the　main　wear　mechanism　is　abrasive　wear.
