The minor addition is fundamental to controlling the formation, manufacture and properties of metallic materials by controlling nucleation during solidification. In the present work, we investigated the effect of minor addition of Sn on glass-forming ability, thermal stability and mechanical property of TiZrCuPd bulk glassy alloy system. The substitution of Cu by 2% Sn improves the glass-forming ability significantly. The Ti 40 Zr 10 Cu 34 Pd 14 Sn 2 bulk glassy alloy rod with a diameter of 12 mm was fabricated by copper mold casting. The Ti 40 Zr 10 Cu 34 Pd 14 Sn 2 bulk glassy alloy exhibits higher energy for crystallization activation (334.3 kJ/mol). The addition of 24% Sn can enlarge the supercooled liquid region, indicating good thermal stability. TiZrCuPdSn bulk glassy alloys exhibit high compressive strength about 20002050 MPa.

Recent Progress in Ti-Based Metallic Glasses for Application as Biomaterials

2013

Ti-based bulk metallic glasses are of great interest in biomedical applications due to their high corrosion resistance, excellent mechanical properties and good biocompatibility. This article reviews recent progress in the development of Ti-based metallic glasses for the application as biomaterials. Ti-based (TiZrCuPd, TiZrCuPdSn, and TiZrCuPdNb) bulk metallic glasses without toxic and allergic elements have been developed. These glassy alloys exhibited high glass-forming ability, high strength, large plasticity, good corrosion resistance and excellent biocompatibility, which open possibilities to create Ti-based metallic glass implants. Using a spark plasma sintering process, large-size Ti-based bulk metallic glasses and the composites with hydroxyapatite, as well as porous glassy alloys having approximate Young's modulus with that of bone were developed.

“…15) Especially a series of Ti-based BMG (Ti 40 Zr 10 Cu 36 Pd 14 ) having high corrosion resistance are recognized as biomedical materials suitable for dental application. 6,7) However, despite of favorable mechanical properties, the BMG cannot be joined directly to human bone due to their relative high chemical stability. Therefore, it is essential to attain biocompatibility (such as bone inducing ability) of the BMG by means of ceramic coating on its surface.…”

Solution Process for Synthesizing Bioactive Nano-Mesh Layer on Ti-Based Bulk Metallic Glasses

et al. 2013

View full text Add to dashboard Cite

Ti based Bulk Metallic Glasses (BMGs) were treated by Hydrothermal (H), Electrochemical (E) and Hydrothermal-Electrochemical (H-E) processes in NaOH solution and all of these processes enabled fabrication of titanate nano-mesh structures on their surfaces. XPS data suggested that the amount of cytotoxic Cu was drastically decreased for the samples treated by H-E process. Specimens having nano-mesh structures on their surface were immersed in Simulated Body Fluid (SBF) for 12 days. The results of the SBF test supported the fact that nano-mesh structures fabricated by these three methods have bioactivity. However, only the specimen treated by H-E process exhibited very good adhesion performance between the induced hydroxyapatite layer and substrate with intermediated titanate nanomesh layer. These results indicated that the H-E process was the best among three to fabricate a low cytotoxic bioactive nano-mesh layer on Ti-based BMG which enabled to induce hydroxyapatite layer with strong adhesion.
