Year: 2024
Type: conference-paper
Abstract: Given the escalating demand for advanced materials capable of withstanding extreme temperatures in the aerospace and automotive industries, the development of enhanced thermal barrier coatings is critical. This study introduces a novel thermal barrier coating material synthesized via the co-doping of yttria-stabilized zirconia (YSZ) ceramics with ceria (CeO2) and scandia (Sc2O3). The aim is to enhance mechanical properties and resistance to calcium-magnesium-alumino-silicate (CMAS) corrosion, both crucial for high-temperature applications in aerospace and automotive industries. Through a comprehensive experimental approach involving solid-phase sintering, microhardness, fracture toughness, and nanoindentation tests, the research evaluates the effects of co-doping on the ceramics’ performance. Results demonstrate that CeO2 and Sc2O3 co-doping remarkably improves the corrosion resistance of CMAS and mechanical properties of YSZ, suggesting potential for next-generation thermal barrier coatings in high-temperature environments.
