High　entropy　alloys　(HEAs)　is　regarded　as　a　newly　wear　and　corrosion　resistant　material　with　multi-component　structures　of　equal　or　near-equal　ratio.　In　this　study,　Ni1.5CrFeTi2B0.5Mox　(x　=　0,　0.25,　0.5,　0.75,　1)　high-entropy　alloys　coating　were　successfully　prepared　by　laser　cladding　technology　to　enhance　the　wear　and　corrosion　resistance　of　civil　commercial　engine　blades.　XRD　test　was　used　to　study　the　structural　characteristics　and　determine　the　crystal　structure　and　their　role　in　HEA　samples.　The　phase　structures,　microstructure,　hardness,　wear　and　corrosion　resistance　of　HEA　coatings　were　specifically　investigated.　The　experimental　results　indicate　that　the　Ni1.5CrFeTi2B0.5Mox　HEAs　display　good　bonding　properties　between　the　substrate　and　the　cladding　layer.　It　has　revealed　that　Mo　addition　will　change　the　coating　structure　from　a　single　BCC　phase　to　a　BCC　+　FCC　dual-phase　structure.　With　the　increasing　Mo　content,　the　corrosion　resistance　of　Ni1.5CrFeTi2B0.5Mox　HEA　coating　is　found　enhanced　in　a　certan　range　in　a　simulated　saturated　salty　water　mud　solution　and　all　the　coatings　exhibit　better　outstanding　corrosion　resistance　than　904　L　stainless　steel　substrate.　It　has　also　found　that　Ni1.5CrFeTi2B0.5Mox　HEA　coating　can　greatly　improve　the　microhardness　and　wear　resistance　of　the　material.　The　highest　average　microhardness　value　(Mo　=　1)　of　HEA　coating　is　673　HV　in　the　rough,　which　is　about　3.6　times　in　the　comprison　with　the　set　substrate.　These　findings　have　a　clear　implication　for　surface　protection　that　Mo0.75　and　Mo1　have　a　lower　volume　wear　rate　and　a　smoother　wear　surface,　performing　better　corrosion　resistance　and　wear　resistance　in　comparison　with　other　coatings.　©　2020　Elsevier　B.V.
