Synthesis of Ti-based glassy alloy/hydroxyapatite composite by spark plasma sintering

Abstract

The spark plasma sintering process has been used to fabricate Ti 40Zr10Cu36Pd14 glassy alloy/hydroxyapatite composites. XRD, DSC, SEM and compression testes were used to examine the microstructure and properties of the composites. No crystallization was observed in the glassy alloy matrix. The glass transition temperature (Tg) is independent of the HA addition and the onset temperature of crystallization (Tx) slightly decreases with increasing HA content. The sintered composite exhibited reduced value of Young's moduli as compared with the as-cast Ti40Zr10Cu 36Pd14 bulk glassy alloy. © 2008 The Japan Institute of Metals.
