Tribological behavior of 1Cr18Ni9Ti steel under hydrogen peroxide solution against different ceramic counterparts

We investigated the effect of counterface of ZrO₂, Si₃N₄ and SiC ceramics on the tribological behavior of 1Cr18Ni9Ti steel in 90% hydrogen peroxide solution. The results show that the tribological properties of 1Cr18Ni9Ti steel are strongly dependent on the counterfaces. The adhesion behavior affects the tribocouple of 1Cr18Ni9Ti/ZrO₂, leading to a high coefficient of friction (COF) fluctuating from 0.17 to 0.27 and the highest wear loss of 1Cr18Ni9Ti steel. The oxidation and hydrolysis protect the worn surface of 1Cr18Ni9Ti/SiC, inducing a low COF 0.035 and the lowest wear loss of 1Cr18Ni9Ti steel. Both the adhesion behavior and the reactions play important roles in the wear behavior of 1Cr18Ni9Ti/Si₃N₄, leading to a complex COF and intermediate wear loss of 1Cr18Ni9Ti steel. As for the counterparts, ZrO₂ ceramic shows the most severe wear, SiC ceramic shows relatively low wear volume, and Si₃N₄ ceramic presents the lowest wear volume.
