The tribological properties of (Al 2 O 3 ) ceramics/1Cr18Ni9Ti stainless steel rubbing pairs were investigated using a MMW‐1 tribo‐tester under pure water and different concentrations of hydrogen peroxide (H 2 O 2 ) solutions. A comparison analysis of the friction coefficient, wear mass loss and worn surface topographies was conducted. The wear mass loss of the 1Cr18Ni9Ti stainless steel ring sample in all H 2 O 2 solutions was greater than that in pure water. The wear mass loss was the highest in 70% H 2 O 2 solution. The comprehensive analysis showed that the main wear mechanisms between the Al 2 O 3 ceramics/1Cr18Ni9Ti stainless steel rubbing pairs were severe adhesive, abrasive and ploughing wear in the H 2 O 2 solutions. It is believed that the knowledge gained in this study will provide the theoretical data and guide for the optimisation of the rubbing pairs in the H 2 O 2 solutions to be used for the lubrication of some moving parts in the propulsion system of the launch vehicle.
