Abstract
► The properties of ZrO 2 , Al 2 O 3 , Si 3 N 4 /1Cr18Ni9Ti were investigated in H 2 O 2 solutions. ► There were significant differences on wear-resistant for three types of ceramics. ► As a whole, Si 3 N 4 /1Cr18Ni9Ti had the best tribological properties in H 2 O 2 solutions. Rubbing pairs of ceramics and stainless steel are widely used under the hydrogen peroxide (H 2 O 2 ) strong oxidizing environment. It is crucial to study the wear behavior and failure modes of the rubbing pairs. The tribological properties of three types of ceramics (ZrO 2 , Al 2 O 3 , Si 3 N 4 ceramics) and 1Cr18Ni9Ti stainless steel rubbing pairs were investigated using a tribo-tester under different concentrations of H 2 O 2 solution. The comparative analysis of the friction coefficients, wear volumes, worn surface topographies and corrosion potentials was conducted under different concentrations of H 2 O 2 solutions. There were significant differences in the tribological and electrochemical properties of the rubbing pairs in different H 2 O 2 solutions. As a whole, the rubbing pairs of Si 3 N 4 ceramics/1Cr18Ni9Ti stainless steel have the best tribological properties in H 2 O 2 solutions. It is believed that the knowledge obtained in this study will provide a guide for the selection of the rubbing pairs in the H 2 O 2 solutions.
