Biocorrosion Evaluation on a Zr-Cu-Ag-Ti Metallic Glass

Metallic glasses are in high demand for fabrication of variety of innovative products, in particular surgical and biomedical tools and devices owing to its excellent biocompatible properties. In the present investigation, a novel Zr_39.5Cu_50.5Ag₄Ti₆ metallic glass composition was synthesized using melt spinning technique. Potentiodynamic polarization studies were conducted to investigate bio-corrosion behaviour of Zr_39.5Cu_50.5Ag₄Ti₆ metallic glass. The test were conducted in various simulated artificial body conditions such as artificial saliva solution, phosphate-buffered saline solution, artificial blood plasma solution, and Hank's balanced saline solution. The bio-corrosion results of metallic glass were compared with traditional biomaterials. The study aims to provide bio-compatible properties of Zr_39.5Cu_50.5Ag₄Ti₆ metallic glass. (paper)
