Notes:
The JMM-ZTA, a kind of zirconia-toughened alumina, is a bearing ceramic newlydeveloped for artificial joints. Although it has already been reported that mechanical strength andfracture toughness are higher in the JMM-ZTA than in alumina, the stability of the JMM-ZTA hasnot been studied in detail yet. In the present study, the stability of the JMM-ZTA with respect tomechanical strength and crystalline phases was examined under hydrothermal environment, andthe results were compared with those of alumina. Both the 4-point bending strength and thefraction of monoclinic zirconia unchanged even after the aging test at 121°C for 300 h. Theseresults indicate that the JMM-ZTA possesses quite excellent stability to be used as bearingmaterial of artificial joints
