High-temperature　wear-resistant　coatings　are　reliable　guarantees　of　key　friction　pairs　of　aeroengines,　and　it　is　urgent　to　further　improve　wear　resistance　of　the　coatings　under　increasingly　harsh　service　conditions.　Therefore,　the　NiCoCrAlYTa　/　ZrO2　/　BaF2　center　dot　CaF2　high-temperature　wear-resistant　coatings　are　prepared　by　laser-assisted　thermal　spraying　technology　and　the　microstructure　evolution　with　the　chemical　composition　analysis　are　studied　by　SEM　coupled　with　EDS　techniques.　Moreover,　the　effects　of　the　mass　fraction　of　ZrO2　/　BaF2　center　dot　CaF2,　laser　power　and　scanning　speed　on　the　microstructure,　mechanical　properties　as　well　as　high-temperature　wear　behaviors　of　the　NiCoCrAlYTa　/　ZrO2　/　BaF2　center　dot　CaF2　coatings　are　investigated.　Results　show　that　the　laser-treated　coatings　exhibit　ZrO2　ceramic　layers　with　dendritic　microstructure　on　the　top　of　the　coatings.　Particularly,　the　coating　containing　25　wt.%　ZrO2　/　BaF2　center　dot　CaF2,　prepared　by　laser　power　of　80　W　and　scanning　speed　of　8　mm　/　s,　exhibits　optimum　performance.　And　with　the　optimized　parameters,　the　coating　exhibits　dense　and　uniform　microstructure,　the　average　value　of　hardness　and　elastic　modulus　could　reach　13.6　GPa　and　182.5　GPa,　respectively,　and　wear　rate　could　reach　2.7x10(-5)　mm(3)　.　N-1　.　m(-1)　after　sliding　under　800　degrees　C.　Also,　the　methodology　of　combining　the　component　design　and　preparation　process　of　high-temperature　wear-resistant　coatings　provides　a　reference　for　properties　of　coatings.
