Kinetic of the Phase Transformation of ATZ Compared to Biograde Y-TZP

Abstract:

Article Preview

Alumina and zirconia ceramics have been successfully used as materials for joint endoprostheses. The present study has been aimed at combining the advantages of the two singlephase materials, Al2O3 and ZrO2 while avoiding their disadvantages, by producing a composite ceramic. Within the scope of a study of an ATZ ceramic we tested the influence of aging by a hydrothermal treatment on strength, phase composition and surface properties. We found that the hydrothermal treatment of the ATZ ceramic did not significantly influence these parameters, unlike those of a single-phase ZrO2 ceramic.
