An　AlCoCrFeNi　high-entropy　alloy　coating　containing　20　%　mass　fraction　of　TiC　was　prepared　using　the　laser　cladding　method.　The　effect　of　heat　treatment　on　the　coating＇s　microstructure　was　analyzed　through　X-ray　diffraction　(XRD),　scanning　electron　microscopy　(SEM),　electron　backscattered　diffraction　(EBSD),　and　transmission　electron　microscopy　(TEM).　It　was　observed　that　following　high-temperature　heat　treatment,　the　phase　transition　of　AlCoCrFeNi-20%TiC　shifted　from　BCC　to　FCC　at　750　°C.　Through　microhardness　and　wear　resistance　tests,　the　increased　diffusion　of　carbon　post-heat　treatment　led　to　a　higher　precipitation　of　TiC-reinforced　phases,　resulting　in　exceptional　wear　resistance　with　a　notable　128.3　%　enhancement.　　©　2024　Walter　de　Gruyter　GmbH,　Berlin/Boston　2024.
