Abstract
- Tribological properties of AlCoCrCuFeNi and AlCoCrFeNiTi 0.5 alloys under 90% H 2 O 2 solution rubbing against 1Cr18Ni9Ti steel, ZrO 2 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 ZrO 2 ceramic, which can be attributed to the lubricating colloidal film formed by tribo-chemical reaction between H 2 O 2 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.
