Microstructures and Mechanical Properties of Biocompatible Ti-35%Nb-2.5%Sn Alloy for Biomedical Applications |
| 초록 |
Ti-35%Nb-2.5%Sn powder was prepared by high-energy ball milling. The particle size, phase transformation and microstructure of the as-milled powder were investigated by particle size distribution(PSD) analyzer, scanning electron microscope(SEM), X-ray diffractometer(XRD), transmission electron microscope(TEM) and differential thermal analysis(DTA). The milled powders were densified by heating up to a sintering temperature varied from 800 to 1100℃ with PCAS(Pulse Current Activated by Sintering). PCAS was effective method to fabricate the fine grain and fully densified Ti-35%Nb-2.5%Sn alloy. The density of the compacts consisting of the milled Ti-35%Nb-2.5%Sn powder increased with increase of sintering temperature, but that of the compacts consisting of Ti-35%Nb-2.5%Sn powder blend only increased with increase of sintering temperature up to 950℃. Microstructural examination of PCAS sintered Ti-35%Nb-2.5%Sn alloy using 4h-milled powder showed Nb-rich phase and Nb-poor phase which are fine and homogeneously distributed. The sintered Ti-35%Nb-2.5%Sn alloy with milled powder showed higher hardness and better wear resistance properties and also biocompatibility than the Ti-6Al-4V alloy. |
