The　AlCoCrCuFeNiMnV0.2Cx(x=0,　0.02,　0.05,　0.1,　0.2,　moleratio)　high-entropy　alloys　cladding　layers　were　prepared　on　Q235　steel　surface　by　plasma　cladding.　The　component,　microstructure,　crystal　structure　and　microhardness　of　the　cladding　layers　were　investigated　by　means　of　XRF,　OM,　SEM,　XRD　and　digital　display　Vickers　hardness　testers.　The　results　indicate　that　the　microstructure　of　the　cladding　layers　is　composed　of　dendritic　segregation.　The　crystal　structure　of　cladding　layers　is　FCC+BCC　duplex　phases,　while　the　dendrite　and　the　interdendrite　are　consisted　of　BCC　and　FCC　phases,　respectively.　When　the　range　of　x　is　0.05-0.2,　abundant　VC　phases　are　precipitated　in　dendrite,　and　the　shape　of　VC　includes　cross　shape　and　polygonal　granular.　The　microhardness　of　cladding　layers　increases　with　increasing　C　content,　furthermore,　the　microhardness　of　the　layer　is　572.4　HV　when　x=0.2,　due　to　the　solid　solution　strengthening　of　C　and　the　precipitation　strengthening　of　VC.　©　2015,　Editorial　Office　of　TRANSACTIONS　OF　MATERIALS　AND　HEAT　TREATMENT.　All　right　reserved.
