The oxidation kinetics of CZA4‐BMG obeyed a multi‐stage parabolic‐rate law, and its steady‐state oxidation‐rate constants were slightly lower than those of Ag‐free amorphous alloy (CZA3‐BMG) at the temperature below 450 °C, indicating that the addition of Ag played a partly blocking effect in reducing the available cross‐sections of the substrate, which in turn reduced inward diffusion of oxygen, thereby leading to the reduction of oxidation rates for CZA4‐BMG. |
