Modified Composites of Al_2O_3-(Ce-TZP) System as Materials for Medical Use

摘要

This article presents an investigation of the influence of modification of Al_2O_3-(Ce-TZP) with alkaline earth elements Ca~(+2) and Mg~(+2) on the phase composition, microstructure, and strength characteristics of composites. It is established that modification of Mg~(+2) compositions leads to a decrease in the strength parameters of composites, while introduction of Ca~(+2) contributes to an increase in the strength parameters of the respective composites owing to aggregation of effects of transformational and dispersive hardening. The obtained high-strength composites can be applied as constructional materials in engineering and medicine.
