Dudziak, P. Datta, P. Mayrhofer, F. Rovere] The oxidation behaviour of Cr0.45Al0.53Y0.02N (at.%) thin film deposited on γ-TiAl based alloy Ti-45Al-8Nb (at.%) was carried out. The tests were performed in the temperature range 750-950°C for 500h. The materials showed good corrosion resistance only at temperatures of 750 and 850°C where Al2O3 and Cr2O3 phases developed as a top oxide scale. A lack of corrosion resistance was observed at 950°C where a thick scale (100μm) that developed consisted of alternate layers of TiO2 and Al2O3 phases. To investigate the oxidation behaviour, the corrosion kinetics were determined by means of discontinuous gravimetry of the exposed samples. Surface and cross-sectional analyses of exposed samples were conducted using scanning electron microscopy (SEM) and energy X-ray dispersive spectroscopy (EDS).
