Abstract

The oxidation behavior of Zr 56Co 28Al 16 bulk metallic glasses was studied over the temperature range of 673-923K. The oxidation kinetics of the metallic glass follows a two-stage or single parabolic rate law from 773K to 923K. Cobalt oxides precipitated on the topmost oxide layer during oxidation. Below the crystallization temperature, the scale formed after oxidation for ten hours was less than 2μm-thickness. The oxidation was accelerated up to 823K, but the oxidation resistance was enhanced at a further increased temperature 923K. The oxidation process was governed by the inward diffusion of oxygen and the outward diffusion of Co. © 2012 Elsevier Ltd.
