Study on Oxidation Behavior of Beryllium Bronze

Abstract

The oxidation behavior of beryllium bronze is studied through phase and component analysis, SEM and other methods in the paper. Make a study on oxidation mass gain law of beryllium bronze between 210°C and 300 °C. Results show that the mass of beryllium bonze gains obviously at the initial time, then gains slowly gradually, which follows approximately parabolic rate law in whole. The oxidation of beryllium bronze is a progress of O spreads to interior of alloy while Be and Cu spread outside. The oxidation products are BeO and CuO, BeO is beneath CuO.
