Sintering behavior of HA/Ti composites

Abstract

The hydroxyapatite/titanium (HA/Ti) composites are considered promising biomaterials for orthopedic applications due to the excellent biocompatibility of HA and good mechanical properties of titanium. Since the HA/titanium composites are normally fabricated through powder metallurgy routes, a clear understanding of the sintering behavior of the composites are essential for the processing and fabrication of the materials. In this study, the sintering behavior of the HA/Ti composites under various conditions was investigated. The effect of the HA concentration, processing parameters such as sintering temperature and time, on the sintering kinetics, porosity, interface reactions, and microstructures will be discussed.Peer reviewed: NoNRC publication: Ye
