The morphology, chemical composition and microstructureof the coating sputtered at540 °Cwere strongly dependent on the substrate microstructure. The two coating variantsformed oxidation-resistant Al2O3 scales during oxidation.

This demonstrates the capability of using MAX phase coatings as erosion protective medium for engine components exposed to similar damage conditions.

This work discusses the thermocyclic oxidation behavior of newly developed β/γ-TiAl alloys at temperatures between 600 °C and 900 °C. An influence of β-stabilizing alloying elements like Nb and V on the oxidation of these alloys has been investigated here. The selected alloys are tested in an in-house developed thermocyclic furnace. The oxidation study is supported by gravimetric measurements along with Scanning Electron Microscopy (SEM) and Electron Diffraction Spectroscopy (EDS) mapping of the oxide layers. Additionally, phase formation after oxidation has been determined using X-Ray Diffraction (XRD). Results show that the Nb containing alloys are more oxidation resistant as compared to V containing alloys. The formation of a mixture of Al2O3 and TiO2 layers was found for all the alloys. The oxide kinetics controlled oxide growth and formation of various phases at different testing temperatures.}, language = {en} }
