“…It was known that Zr-based metallic glass shows excellent corrosion resistance because of forming stable Zr-based passivation film. [20][21][22] Besides, Al is also a strong passivating element. In addition, Qiu et al 25 Gd 10 showed no durability in this static immersion durability study in artificial saliva.…”

Exploitation of metallic glass as new brazing filler for Ti-based biomedical alloy was attempted. Ni 10 P 20 joint showed the excellent properties in terms of both corrosion resistance and tensile strength, which were superior to a joint brazed using Ti-15Cu-25Ni conventional filler. X-ray tomograph indicates that fracture tends to occur in the vicinity of the brazing interface after tensile test.The brazed metallic glass fillers were fully crystallized, excluding Pd 40 Cu 30 Ni 10 P 20 filler. Pd 40 Cu 30 Ni 10 P 20 brazed filler contained mapleleaf like primary dendrite, peritectoid and a few microns interfacial reaction layer in glassy matrix. The results indicated that Pd 40 Cu 30 Ni 10 P 20 is promising brazing filler for dental or biomaterial devices.

“…2 BMGs comprise transition metals that are often combined with metalloids, which are then combined in a multicomponent alloy. 3,4 The amorphous structure results in very high strength and elasticity, properties that are often paired with toughness, 5 flaw tolerance, 6 high corrosion resistance, [7][8][9][10] biocompatibility, [11][12][13] and favorable electrochemical behavior. 14 These properties have triggered wide commercial exploration of BMGs.…”

“…In addition, for practical applications, the surface modification which enables the fabrication of bioceramic layer having less or no Cu elements would be required. 8) Recently, the formation of bioactive titanate layer on Ti 40 Zr 10 Cu 36 Pd 14 by Hydrothermal-Electrochemical process was reported. 9) This technique has the advantage of a processing temperature typically less than 423 K, which is low enough to avoid crystallization of Ti-based BMG.…”

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.
