Isothermal Oxidation Behavior of Cu-38at.%Zn Alloy at High Temperature
The isothermal oxidation behavior of Cu-38at.%Zn alloy over the temperature range of 773–1123 K was studied. Characterization of the oxidized specimens was conducted using X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the oxidation kinetics of Cu-38at.%Zn allo...

| description | The isothermal oxidation behavior of Cu-38at.%Zn alloy over the temperature range of 773–1123 K was studied. Characterization of the oxidized specimens was conducted using X-ray diffraction (XRD) and scanning electron microscope (SEM). The results show that the oxidation kinetics of Cu-38at.%Zn alloy obeys parabolic law. The activation energy during oxidation of the alloy is calculated to be 176 kJ mol–1, based on the parabolic growth constant analyses. An external ZnO oxide scale, internal ZnO oxide and a Zn depletion zone on substrate formed after alloy oxidation are discussed. The scale spallation from the substrate is analyzed, based on the growth stresses and thermal stresses induced during oxidation. |
