Abstract

Abstract Tribological properties of AlCoCrCuFeNi and AlCoCrFeNiTi_0.5 alloys under 90% H₂O₂ solution rubbing against 1Cr18Ni9Ti steel, ZrO₂ ceramic and SiC ceramic were investigated. The tribological behavior is dependent on the counterparts and the structure of high entropy alloys. The high entropy alloys exhibit significantly lower friction coefficient and wear loss sliding against SiC ceramic than 1Cr18Ni9Ti steel and ZrO₂ ceramic, which can be attributed to the lubricating colloidal film formed by tribo-chemical reaction between H₂O₂ and SiC. Moreover, the AlCoCrFeNiTi_0.5/SiC tribo-pair preserves better tribological properties than AlCoCrCuFeNi/SiC tribo-pair, as results of high strength and hardness of AlCoCrFeNiTi_0.5 alloy.
