Abstract :
The corrosion resistance of (Zr56Al16- Co28)100-XNbX(X = 0, 2, 4) metallic glasses in Hanks’ solution were investigated by electrochemical polarization
measurements. Polarization curves demonstrate that the
addition of niobium into Zr–Co–Al amorphous alloys
improves the corrosion resistance. Composition and
chemical status of the elements in the passive film were
characterized by XPS, and first-principles calculations
based on density functional theory (DFT) were used to
analyse the mechanism theoretically.
