Dry-sliding tribological properties of AlCoCrFeNiTi0.5 high-entropy alloy
文献摘要：
High-entropy alloys(HEAs),with a new alloy-ing concept,could possess many unique mechanical and functional properties.The current work investigated whe-ther one such alloy offers potential for bearing surfaces under dry conditions.The dry,reciprocating sliding wear characteristics of AlCoCrFeNiTi0.5 alloy were investigated under various applied loads and sliding speeds.Transmis-sion electron microscopy(TEM)and scanning electron microscopy(SEM)were utilized to characterize internal structure and wear surfaces of the alloy,respectively.It is found that the AlCoCrFeNiTi0.5 alloy preserves better wear resistance than Fe77Ni23 solid solution alloy,Ti-46Al-2Cr-2Nb intermetallic alloy,or a wear-resistant steel AISI 52100,especially under higher loads.The wear rate increases slowly with the applied loads increasing and keeps steady under different sliding speeds.The wear mechanisms are abrasive wear,adhesive wear and oxida-tive wear.The nano-sized Fe-Cr solid solution and Al-Ni-Ti rich intermetallic phase precipitated in the dendritic regions and the formation of oxidation play important roles in the good wear resistances of this high-entropy alloy.
