Notes:
A slurry pot tester was used to evaluate the erosion behavior of alumina (Al2O3), zirconiatoughened alumina (ZTA), and silicon nitride ceramics. The eroded surface of sample was studied byscanning electronic microscope and the primary erosion wear mechanisms for ceramic materials wereanalyzed. On the same experimental condition, erosion wear resistance of materials follows this rule:Si3N4〉ZTA〉Al2O3. The key factor affecting erosive wear performance of ceramics is their microstructure.The primary erosive wear mechanisms for Al2O3, ZTA and Si3N4 ceramics are lateral crack propagation,whole grains pulled out and plastic deformation. The erosive wear performance of Si3N4 ceramic is thebest in this experiment, due to their microstructure morphology with elongated grains
