Abstract
PSZ-Ti composites consisting of partially stabilized zirconia (PSZ) and pure titanium (Ti) were fabricated by spark plasma sintering (SPS), and their mechanical properties were evaluated. According to the X-ray diffraction (XRD) analysis, Ti2O and Ti2ZrO were detected on all composites and pure Ti was detected on the composites with Ti volume fraction more than 90%. The Vickers hardness and Young’s modulus were higher than the predictions by rule of mixture. The bending strength and fracture toughness of the composites decreased up to 75%Ti and then increased with increasing Ti content. It was proposed that these results were caused by hardening and embrittlement due to the reaction phases such as Ti2O and Ti2ZrO.
