Wear behavior of different SiC and WC reinforced high entropy alloys deposited by the spark emmission procedure on a AISI 1010 steel

Abstract In this study, CrMnFeCoNi (HEA) coating electrodes containing different proportions of reinforcement elements were produced by arc melting reverse vacuum system and the steel surface was coated by electro-spark deposition (ESD) method. According to the obtained data; while the microstructures for unreinforced HEA consisted of FCC structure, M 7 C 3 , M 23 C 6 and phases belonging to reinforcement elements were detected together with FCC structure in SiC and WC reinforcement. Good bonding was detected at the matrix-coating interface and layer thicknesses varied between 18 µm and 60 µm, and micro hardnesses varied between 256 HV and 578 HV. According to the wear tests, the steel wear rate decreased up to 32 times depending on the reinforcement element ratio and type.
