Thermal　sprayed　high　entropy　alloy　coatings　have　garnered　substantial　attention　for　their　remarkable　mechanical　properties　and　wear　resistance.　In　this　study,　we　explored　the　wear　behavior　and　mechanisms　of　Al0.6TiCrFeCoNi　coatings　produced　through　atmospheric　plasma　spray　(APS)　at　both　room　temperature　and　500　°C.　The　microstructural　and　mechnical　characterization　of　the　APS-sprayed　coating　was　performed　using　XRD,　OM,　SEM,　CSLM　and　hardness　testing　techniques.　The　dry　sliding　wear　test　of　the　coating　against　Al2O3　ball　were　conducted　on　a　pin-on-disc　tribometer　at　room　temperature　and　500　°C.　The　coating　exhibited　a　single　body-centered　cubic　(BCC)　phase,　with　a　typical　lamellar　structure　marked　by　oxides　and　pores.　Wear　tests　showed　that　the　APS-sprayed　coating　exhibits　superior　wear　resistance　at　elevated　temperatures　compared　to　room　temperature　due　to　the　formation　of　compact　oxide　layer　on　the　wear　track.　Detailed　investigations　on　wear　track　reveal　that　abrasive　wear,　oxidation　wear　and　fatigue　wear　are　the　prominent　wear　mechanisms　on　both　conditions,　while　tribo-oxidation　is　dominated　at　500　°C.　Furthermore,　We　demonstrated　that　the　looser,　more　porous　microstructure　of　the　APS-sprayed　coating　contributes　to　its　enhanced　wear　resistance,　preventing　crack　propagation　and　increasing　strain　tolerance.　This　provides　a　promising　strategy　for　outstanding　wear　resistant　coatings　by　designing　looser　lamellar　coating　structure.　©　2023　Elsevier　B.V.
