Erosion resistance of CaO−Al₂O₃−SiO₂ system glass-ceramics

Abstract

The erosion resistance tests were used to research the erosion wear behavior of CaO−Al₂O₃−SiO₂ system glass-ceramic. With the orthogonal test method, the factors that affect the erosion wear of CaO−Al₂O₃−SiO₂ system glass-ceramic such as particles property, impact angle, impact time, size of particles were discussed. The results show that erosion rate rises along a straight line at the early period of erosion wear. With the impact time increased, the erosion rate deviates from original staight line, tendency of the erosion rate increases. With the size of paricle increased, it will have more kinetic energy, the erosion rate of the surface of glass-ceramics ploate rises.
