Bio-corrosion studies of Fe-based metallic glasses

Abstract Fe-based metallic glasses are known for their high corrosion resistance. Also, the corrosion resistance of metallic glasses are greatly influenced by the alloying elements. In the present study, the bio-corrosion resistance of two Fe-based metallic glasses (Fe32Ni36Cr14P12B6 and Fe67Co18B14Si1) has been studied. The bio-compatibility of these metallic glasses are studied in four simulated body fluids (SBFs), namely artificial saliva solution (ASS), phosphate-buffered saline solution (PBS), artificial blood plasma solution (ABP), and Hank’s balanced saline solution (HBSS). Potentiodynamic polarization studies are performed on both the metallic glasses, for understanding their bio-compatibility.
