Abstract

The solid state oxidation kinetics of Pb-In single-phase alloys were studied using AES (Auger Electron Spectroscopy) combined with sputter depth profiling. Samples containing 3, 30, 64 at% In were oxidized in air from room temperature up to 275 °C. At room temperature, the oxidation behavior for all three alloys was found to obey a direct logarithmic law. As the temperature is increased, the kinetics change from logarithmic to parabolic behavior. The transition between logarithmic and parabolic kinetics occurs between 150 °C and 175 °C for Pb-3 at% In alloy, and below 100 °C for Pb-30 at% In and Pb-64 at% In alloys. Using the solidius temperature as melting temperature of an alloy, the transition temperature for Pb-In alloys was observed to be approximately 70 – 75 % of the melting temperature.
