Abstract

This research is aimed to determine the best composition of composite fabricated by Spark Plasma Sintering (SPS) to produce a suitable substituent for bone. The applied powder was prepared by the SPS method and comprises hydroxyapatite (HA), yttria-stabilized zirconia (YSZ), and titanium (Ti). Different percentages of components were used to fabricate the composite samples. X-ray diffraction was used to determine the structural phase of the sintered samples while field emission scanning electron microscopy (FE-SEM) was employed for microstructural analysis of the specimens. The behavior of the samples was investigated during sintering. The gas release, displacements, and porosity percentage of the composite samples were also explored. Three-point bending test was utilized to determine the flexural strength whereas the hardness of the samples was determined by the Vickers method. Moreover, the CHANTIKUL method was used to evaluate the toughness of the samples. The results showed the best mechanical properties in the 90%HA-6%YSZ-4 %Ti sample.
