“…The regional enrichment of O implied the formation of corrosion products. The EDX measurements indicated that the corrosion process of the ZrAlFeCu BMG was similar to the one proposed in our previous studies, which involved the breakdown of passive film due to Cl À attack, the preferential dissolution of alloying elements and the formation of metastable CuCl and subsequent CuO as a result of hydrolysis [34,35].…”

Vascular stents are medical devices typically used to restore the lumen of narrowed or clogged blood vessel. Despite the clinical success of metallic materials in stent-assisted angioplasty, post-surgery complications persist due to the mechanical failures, corrosion, and in-stent restenosis of current stents. To overcome these hurdles, strategies including new designs and surface functionalization have been exercised. In addition, the development of new materials with higher performance and biocompatibility can intrinsically reduce stent failure rates. The present study demonstrates the advantages of a novel material, named bulk metallic glass (BMG), over the benchmarked 316L stainless steel through experimental methods and computational simulations. It raises the curtain of new research endeavors on BMGs as competitive alternatives for stent applications.

“…4d, SEM examination of the corroded ZrAlFeCu BMG sample revealed the formation of corrosion pits on the surface and the typical honeycomb structure within the pit, which was commonly observed in the corrosions of Cu-containing Zr-based BMGs [34,35]. EDX mapping in Fig.…”

“…The co-implanting of Cr and O in Mg has been studied [71]. Bulk metallic glass alloys, such as Ca-Mg-Zn show good degradation and material properties, however the narrow range in which their high temperature formation occurs may make it difficult to use additive manufacturing technologies [72][73][74][75].…”

“…Resulting from their amorphous microstructure, Zr-based bulkmetallic glasses (BMGs) exhibited a unique combination of excellent mechanical and electrochemical properties [1][2][3][4][5][6][7][8], which prompted a great interest in their biomedical applications, especially as medical implants. However, the human body environment is aggressive to implants.…”
