The effect of SrSO4 content on the tribological properties of NiCr–30wt%ZrO2(Y2O3) (NC30Z) cermet was evaluated over a wide temperature range from room temperature to 1000°C. The results indicated that the inclusion of SrSO4 effectively improved the friction coefficients and wear rates of NC30Z cermet above 400°C. NC30Z–5SrSO4 composite against alumina ball exhibited satisfactory tribological performance,...
