The aim of this study is to
determine the high temperature cyclic oxidation behavior of boron carbide (B₄C)
in air atmosphere at elevated temperatures. For this purpose, as-received
powders were firstly characterized by XRD and SEM. Boron carbide powders were
shaped by cold pressing for oxidation studies. Tests were performed in air
atmosphere at 800˚C and 1000˚C for 5, 10, 15 and 20 hours. After each oxidation
test, the mass changes were measured. XRD, SEM and EDS analyses were conducted
on the oxidized samples and the results were discussed. It was observed that
cyclic oxidation behaviors of the samples depended on temperature and time.
Based on the analyses results and the microstructure observations,
volatilization of B₂O₃ had significant effect on the
oxidation of the samples as the temperature increased.
