摘要：

Ti-based amorphous alloys Ti70Zr6Fe7Si17 (at.%) and Ti64Zr5Fe6Si17Mo6Nb2 (at.%) are fabricated by a single roller spun-melt technique. The feature of the alloy composition satisfies Inoue's three empirical rules. Amorphous structures of the both alloys were confirmed by the X-ray diffraction patterns. The both alloys were cultivated in the simulate body fluid (SBF) for 15 days and the experiment result shows that Ca phosphates depositions on alloys surfaces were gained. Moreover, n(Ca)/n(P) atom ratio of the deposition is about 1.6/1, which approach to that of human bone - 1.66/1, suggesting that the both alloys were with an excellent biocompatibility.
