Abstract

High-concentration hydrogen peroxide solution (HCHP) was regard as potential fuel resources. However, mechanical wear of moving parts under HCHP was energy-wasteful and dangerous. This work designed a novel SiC ceramic/AlCoCrFeNiTi_0.5 high-entropy alloy tribo-pair, which successfully achieved outstanding self-lubrication under HCHP. The lubrication behavior of the proposed tribo-pair mainly benefitted from three aspects: (i) oxidation and hydrolysis reactions of SiC ceramic, (ii) hydrodynamic and secondary lubrication effects of surface pores, (iii) inhibited adhesion behaviors between SiC ceramic and AlCoCrFeNiTi_0.5 alloy. Rounding the pore edges of SiC ceramic further improved the load-carrying capacity of self-lubrication. The wear bottleneck problem under harsh HCHP was solved in this work.
