Abstract
In this paper, effects of temperature and erosion-wear particle on solid particle erosion-wear behavior of alumina ceramics were studied. The erosion-wear experiments were performed using self-designed sand blasting high-temperature solid particle erosion-wear equipment in air atmosphere. The results show that alumina ceramics presented the characteristics of brittle fracture at the high temperature of 1200°C. Erosion-wear rate increased with increasing temperature and rise obviously above 1000°C. For the same kind of erosion-wear particles, the erosion-wear rate of samples increased with the larger particle size. For the different ones, the greater hardness, the more serious erosion-wear.
