Abstract
In the present work, hydroxyapatite (HAP) and zirconia (ZrO2) powders have been used to elaborate HAP-ZrO2 composite for biomedical applications. X-ray diffraction (XRD), and scanning electron microscopy (SEM)), were used to characterize the as-obtained samples. The aim of this study was to evaluate the morphology, densification and mechanical strength of the produced ceramics sintered at 1200 °C and 1250 °C. The relative density and mechanical strength of the HAP-ZrO2 ceramics reached their height values at 1250 °C. Experimental results were modeled by the finite element method to determine the stress distribution in the compacted samples. In addition, the stress intensity factors in produced ceramics for different geometrical dimensions of the notch was evaluated numerically.
