Electrochemical behavior of a Ti-based bulk metallic glass

Review on the Research and Development of Ti-Based Bulk Metallic Glasses

“…In general, the corrosion-penetration rates (CPRs) of less than~76 µm/year are considered acceptable for chemical and industrial applications. According to Morrison et al's research [218], the CPR of Ti 43.3 Zr 21.7 Ni 7.5 Be 27.5 BMG in a PBS electrolyte at 37 • C is 2.9 ± 2.6 µm/year, which is well within the expected range for corrosion resistant materials and equivalent to, or better than, Zr-based BMGs and 316L stainless steel. Except for PBS, Ti-based BMGs also exhibit good bio-corrosion resistance in other simulated body fluids such as SBF, Ringer's solution, and Hanks' solution [219].…”

The Way from Today's Materials to New Kinds of Amorphous Solids: Nano-glasses

“…Thus, substantial efforts were devoted to the development of biocompatible Ti-based bulk metallic glasses (BMGs) (Linde 1966;Ma 2003;Hauser 1975;Nastasi et al 1985). However, without Ni -which is toxic to the human body -Ti-based alloys generally exhibit a lower glass-forming ability (Oak et al 2007;Morrison et al 2007, Qin et al 2007) than the other metal-based BMGs, for example, Zr-based, Cu-based or Fe-based alloys.…”

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

“…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.…”
