Hydroxyapatite와 TiNx의 복합체의 제조

Abstract

The composites of hydroxyapatite-TiNx were prepared using a spark plasma sintering(SPS) apparatus. Density of hydroxyapatite-1%TiNx composite was decreased with increasing content of TiNx in order of 0.1%, 05% and 1.0% but density of hydroxyapatite-1%~10%TiNx composite was increased with increasing content of TiNx inorder of 1%, 5% and 10%. The maximum biaxial strength of hydroxyapatite and TiNx of composites was achieved by SPS with a composition of 0.1% TiNx at 900oC. The decomposition of composites hydroxyapatite and TiNx composites were not detected by XRD at the range of 900oC to 1100oC, this means the decomposition of hydroxyapatite was restrained easily by addition of TiNx.
