SYMPOSIUM 2: Advanced Ceramic Coatings for Structural, Environmental, and Functional Applications

Advanced ceramic coatings extend lifetime or even enable operation of engineering materials in harsh environments. Consequently, the continuous research and development of new high-performance protective coating systems minimizing degradation of materials and components is highly relevant. Advanced gas turbine engine components made of ceramic matrix composites, intermetallics, or superalloys promise higher efficiency due to increasing operation temperatures. However, the synergistic attack of heat, combustion atmosphere, and inorganic, CMAS-type aerosols is strongly affecting lifetime. Oxidation protection is a key issue for ultra-high temperature ceramics and composites used in reusable spacecraft or hypersonic vehicles. Furthermore, protection of metals against oxidation, corrosion, erosion, and wear by innovative ceramic coatings is also a key technology for many industrial fields such as mining or waste treatment. Functional ceramic thin films are used in electronics and solar power generation. The symposium addresses processing, microstructure, performance, and durability of advanced ceramic coating systems. Advanced and new coating compositions, innovative processing technologies, advanced characterization methods and thermodynamic modeling are particularly emphasized. Material scientists and engineers from around the world are invited to present and discuss their recent advances in ceramic coating sciences and technologies.

A dedicated session on environmental barrier coatings for ceramic matrix composites will be held in memory of our late colleague Dr. Dongming Zhu (NASA GRC).
