High-entropy　alloys　(HEAs)　are　promising　as　a　new　type　of　engineering　material　with　extensive　research　value.　Rare-earth　elements　are　widely　studied　and　used　to　prepare　HEAs　because　of　their　unique　properties.　In　this　work,　the　MgMoNbFeTi2Yx　(x　=　0,　0.4%,　0.8%　1.2%)　HEA　coatings　were　manufactured　by　laser　cladding　technology.　The　effect　of　Y　on　the　phase　structure,　microstructure,　wear　resistance,　microhardness　and　corrosion　resistance　of　the　laser　cladding　coatings　were　investigated　methodically.　As　a　result,　the　coating　samples　exhibit　brilliant　bonding　abilities　between　substrates　and　claddings　layer　with　Y　additives.　When　Y　content　is　low,　the　phase　composition　consists　of　a　face　centered　cubic　(FCC;　Mg,　Ti-rich　(Nb,　Ti)　C　carbide)　and　biphasic　body　centered　cubic　(BCC)　solid　solution.　With　an　increment　in　Y　content　(Y　=　0.8%/1.2%),　the　phase　composition　is　composed　by　one　BCC　phase　along　with　FCC.　In　the　simulated　saturated　saline　cement　solution,　corrosion　resistance　of　the　HEA　coating　is　enhanced　by　Y　addition.　In　addition,　the　MgMoNbFeTi2Y0.8%　HEA　coating　show　an　excellent　corrosion　resistance.　The　MgMoNbFeTi2Y1.2%　HEA　coating　displays　the　highest　average　microhardness　of　about　1046　HV0.3,　which　is　2.7　times　stronger　than　that　of　the　coating　without　Y　content　(Y　=　0)　and　more　than　5　times　higher　than　that　of　the　average　microhardness　of　the　base　material.　More　interesting,　such　HEA　coating　shows　an　excellent　wear　resistance.　This　work　can　provide　a　novel　and　effective　approach　to　significantly　improve　the　surface　quality　of　the　characteristics　of　HEAs,　which　will　promote　them　further　applications　as　a　promising　candidate　material　in　advanced　manufacturing　fields.　©　2020　Elsevier　B.V.
