Abstract: Abstract:This work studied the oxidation behavior of a Ag-containing Cu–Zr–Al-based amorphous alloy (CZA4-BMG) in dry air at 375–500 °C. 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.
