Résumé
La résistance à la rupture et la ténacité des céramiques à base d'alumine est renforcées par ajout de ZrO2 (Y2O3) et de matériaux monoxydes tels que SiC, TiC, TiN et B4C. Un renforcement et un durcissement importants sont ainsi obtenus dans les composites Al2O3-ZrO2-SiC et Al2O3-ZrO2-TiC.
Abstract
Strength and toughness of Al2O3 based ceramics were improved by dispersing ZrO2 (Y2O3) and nonoxide materials such as SiC, TiC, TiN and B4C. Significant toughening and hardening were attained in Al2O3-ZrO2-SiC and Al2O3-ZrO2-TiC composites.
