The oxidation behaviour of Ti3SiC2 in air is not well understood due to mixed results reported in the literature. In this study, the surface composition depth-profiles of air-oxidized Ti3SiC2 have been investigated by synchrotron radiation diffraction (SRD) and secondary ion mass spectroscopy (SIMS) in the temperature range 500-1300°C. Anatase has been observed to form at ~600°C, rutile at ~750°C and tridymite at ~1100°C. Depth-profiling results by SIMS and SRD have revealed a distinct gradation in element and phase composition respectively within the surface oxide layers.
