To study the improvement in solid particle impact erosion wear resistances of 3 mol% yttria‐stabilized zirconia (3YSZ) ceramic at elevated temperatures up to 1400°C, 2 wt% LaMgA1 11 O 19 was added into 3YSZ to prepare LaMgA1 11 O 19 ‐3YSZ ceramic for erosion resistance tests with angular corundum abrasive particles. The testing results show that the volume erosion rates of 3YSZ and LaMgA1 11 O 19 ‐3YSZ ceramic were similar in the temperature range from room temperature to 600°C, then exhibited a sharp increase from 600°C to 1200°C, and dropped again at 1400°C. It was mainly caused by the change in material removal mechanisms from plastic deformation below 600°C to the interaction of transverse cracks in the temperature range from 600°C to 1400°C. The solid particle impact erosion wear properties of 3YSZ ceramic in the temperature range from 600°C to 1400°C were successfully improved by the addition 2 wt% LaMgA1 11 O 19 platelets. Comparing with the volume erosion rate of pure 3YSZ ceramic (0.687 mm 3 /g) at 1200°C, the value of LaMgA1 11 O 19 ‐3YSZ ceramic (0.551 mm 3 /g) has been decreased by 20%.
