Mechanical Properties of Zirconia-Titanium Composites

Abstract

This study aims to investigate mechanical properties of ZrO 2 -Ti composites. The samples have been fabricated by spark plasma sintering (SPS). The experimental results demonstrate that a small amount of ZrO 2 can enhance Ti matrix in hardness and tensile strength, while a large amount of ZrO 2 degrade the tensile strength and ductility because of high extent of formation of titanium oxide. The mechanical properties of ZrO 2 -Ti composites can be related to thermo-mechanical behavior of ZrO 2 /Ti functionally graded materials (FGMs). In the FGMs, titanium oxide has also formed, which can largely influence thermo-mechanical behavior of the FGMs.
