Abstract
In the quest of corrosion-resistant biomaterials, the emergence of metallic glasses is a welcome stimulus, however, their progress is potentially impeded by the complex fabrication routes. This paper explores a Zr40Ti35Ni14Nb11 metallic glass, developed through combinatorial magnetron co-sputtering. Structural characterization of the system via Grazing-Incidence X-Ray Diffraction and Transmission Electron Microscopy coupled with Fourier Transformation demonstrate single phase homogeneous amorphous structure. The metallic glass, upon comparative electrochemical examination in physiological solution, displays relatively better corrosion resistance properties than conventional biomaterials, i.e. stainless steel 316L and commercially pure titanium, by an order of magnitude lower corrosion current density, (17 nA/cm2), lower passive current density (3.1 ?A/cm2), invulnerability to pitting corrosion and one-order higher charge transfer resistance (6.9 M?
