Abstract

Oxidation kinetics of a Zr ₅₅Cu ₃₀Al ₁₀Ni ₅ bulk metallic glass (BMG) and its crystalline counterpart were studied under dry artificial air at 673 K for long oxidation duration by thermogravimetry analysis (TGA). Oxidation kinetics was observed to follow a parabolic-rate law for the crystalline counterpart and a three-stage behaviour for the BMG. The ionic diffusion mechanism was investigated by using a two-stage oxidation treatment ( ¹⁶O ₂ oxidation and then ¹⁸O ₂ oxidation). The evident solute penetration zone and ion diffusion characteristic through the oxide scale were determined by Cs ⁺ secondary ion mass spectrometry (SIMS) depth profile. The results of ion evolution indicated that the oxide grew under concurrent inward oxygen and outward Zr diffusions in short-term stage of the BMG oxidation; and the oxidation kinetics was controlled mainly by outward Cu and inward O diffusions in the case of long-term oxidation process.
