Wear and friction behaviour of yttria stabilised zirconia coatings are very sensitive to the structure of the material and test parameters such as temperature, applied load, sliding speed, and environment. The present study describes the friction, and sliding wear behaviours of plasma sprayed yttria stabilized zirconia coating (ZrO₂-8wt.%Y₂O₃ (YSZ) deposited on a stainless steel substrate with NiAl bond coat. Tribological properties of the coating were assessed under lubrication condition at loads of 4N and 8N. The frictional behaviour of coating was assessed at a constant temperature of 50°C, while wear characteristics of the coating were investigated at 50°C and 100°C. The experimental results of this study showed a slight decrease in frictional coefficient with increasing load. However, the coating wear rate was slightly increased with increasing load and temperature. The coating wear mainly involved materials transferred from the counter body and pulling-out from the coating material.
