Mechanical and erosion-resistance properties of slag α-sialon ceramics

Mechanical Properties and Solid Particle Erosion Behavior of LaMgAl11O19–Al2O3 Ceramic at Room and Elevated Temperatures

“…A similar trend was also observed by other researchers, and it is not difficult to understand the result because the direction of impacting particles greatly determines the ways of particle-surface collisions during the erosion process and because the ratio of vertical to horizontal components of impact energy varies with the particle impinging angle. 6,12,15,27 At shallow angle erosion, the kinetic energy of the impacting particles primarily contributes to the plowing action and very little to normal repeated impacts, whereas at higher angles of incidence, the kinetic energy of the impacting particles mainly contributes to repeated impacts. As the impingement angle increases, the wear conditions become more severe.…”
