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

High-performance ceramic coating systems are key to current and future technologies. Ceramic coatings extend lifetime or even enable operation of engineering materials in harsh environments. Advanced gas turbine engine components made of ceramic matrix composites, intermetallics, or superalloys promise higher energy efficiency due to increasing operation temperatures. Advanced thermal and environmental barrier coatings (T/EBC) are key to protect components against the synergistic attack of heat, combustion atmosphere, and inorganic, CMAS-type aerosols. Ceramic coatings are crucial for oxidation protection of non-oxide, ultra-high temperature ceramics and composites to be used in reusable spacecraft or hypersonic vehicles. Protection of metal components against oxidation, corrosion, erosion, and wear by innovative ceramic coatings is also a central building block for many other technologies. Functional ceramic coatings are essential for many renewable energy applications.  

The symposium covers processing, microstructure, performance, and durability of advanced ceramic coatings. Research and development on new materials, innovative processing technologies, advanced characterization methods, and modeling are particularly emphasized. Material scientists and engineers from around the world are invited to present and discuss cutting-edge ceramic coating science and engineering.
