Summary:Title screen
The paper presents the results of a study of high-temperature oxidation in air of the metal-ceramic layered Ti3Al(Si)C2/Ta composites. The composites were made of preceramic papers filled with Ti3Al(Si)C2 and metal foils (Ta) by spark plasma sintering. The sintering temperature was 1250°C, the holding time was 5 min, and the pressure was 50 MPa. The corrosion resistance of the laminated Ti3Al(Si)C2/Ta composites was estimated based on the results of high-temperature oxidation in air. The phase composition and microstructure of the oxide layers were analyzed by X-ray diffraction and scanning electron microscopy, respectively. It has been found that the Ti3Al(Si)C2/Ta composites demonstrate high oxidation resistance in the temperature range 800–1200°C due to the formation of a dense Al2O3 layer on the outer surface of Ti3Al(Si)C2. With an increase in the oxidation temperature to 1300°C, a complex oxide layer is formed, consisting of an outer TiO2/SiO2/Al2TiO5 layer and an inner TiO2/Al2O3 oxide layer. The thickness of the TiO2/Al2O3 oxide layers formed on the surface of the Ti3Al(Si)C2/Ta composite at oxidation temperatures up to 900°C is less than 1 μm, at a temperature of 1200°C the thickness of the oxide layers is 3.5 μm, and at 1300°C it is 56 μm
