Synthesis of Ti-Based Glassy Alloy/Hydroxyapatite Composite by Spark Plasma Sintering

Abstract

The spark plasma sintering process has been used to fabricate Ti₄₀Zr₁₀Cu₃₆Pd₁₄ 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 (T_g) is independent of the HA addition and the onset temperature of crystallization (T_x) slightly decreases with increasing HA content. The sintered composite exhibited reduced value of Young’s moduli as compared with the as-cast Ti₄₀Zr₁₀Cu₃₆Pd₁₄ bulk glassy alloy.
