Abstract High entropy alloy (HEA) coatings deposited via graphene powder mixed Micro EDC process, demonstrates enhanced corrosion resistance of Mg-alloys for implant applications. Utilizing a present process, the HEA coatings have been prepared and conducted detailed analyses of their morphology, corrosion and tribological properties. Present work reveals that (CoCuFeMn) 90 Ti 5 Al 5 HEA coating substantially impacts corrosion resistance and wear resistance properties. Notably, the (CoCuFeMn) 90 Ti 5 Al 5 coating was identified as most effective, with a corrosion penetration rate (CPR) of 9.6 mm/year as determined by electro chemical workstation. Further, the tribological properties are also improved by using graphene nano powder during the coating process.
