A novel high entropy alloy (HEA), designated as HE6, is created based on Stellite 6 in this research. The new alloy has the equiatomic Co-Cr-Fe-Ni composition with a large amount of W and other minors. The bulk specimens are fabricated from the alloy powder via spark plasma sintering (SPS) and plasma transferred arc (PTA) welding. The microstructures of the specimens are studied using XRD and SEM equipped with EDX. A series of material characterization tests such as hardness, wear and corrosion are performed on the bulk HE6 specimens as well as Stellite 6 specimens. It is found that HE6 alloy has a similar microstructure compared to Stellite 6. However, the solid solution of HE6 consists of multi-element FCC structures rather than single FCC Co structure. As for the performance evaluation, Stellite 6 has better overall performance than HE6. And the effect of processing methods is not obvious.
