| description | High-entropy alloys (HEAs) are prospective advanced materials for the production of components that operate at high, severe friction and in high-temperature environments. This is because they possess unique properties requisite for such applications. Hence, this study was aimed at reviewing most recent publications on the tribological characteristics of HEAs processed with spark plasma sintering (SPS). The choice of SPS was because it impacts alloys with a homogenous microstructure, high wear resistance, densely packed grains, and nanocrystalline microstructure. The resource materials for this study were obtained from the Scopus-indexed journal/Google Scholar website for articles published within the last five years. From the study, it was observed that HEAs have good tribological properties which permit their prospective usage in the production of strength-demanding, wear-demanding, and temperature-demanding components. The addition of BCC-forming and FCC-forming elements would help in improving the wear properties of HEAs. It was also observed from the literature that the incorporation of post-processing treatment, laser cladding, shot peening, or the coating of SPSed composites would increase the effective performance and durability of HEAs prepared with SPS. |
