The present work compares the behaviour of four steels: (T23, T92, T347HFG, Super304H) in the temperature range 600–750 °C. This study focuses on the analysis of the oxidation kinetics in terms of mass change, metal loss and thickness change of the selected materials. In order to understand the differences in oxidation rates between the selected steels, the impact of chromium and the alloying elements...
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 500 h. 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...
