Thermal Barrier and Environmental Barrier Coatings for High-Temperature Turbines and Engines
This community develops ceramic and composite coatings designed to protect metal substrates from extreme heat, oxidation, and corrosive environments in gas turbines, jet engines, and industrial machinery.
The work centers on the synthesis, deposition, and testing of thermal barrier coatings (TBCs) and environmental barrier coatings (EBCs). Recurring materials include yttria-stabilized zirconia (YSZ), rare-earth oxides, and high-entropy ceramics. Common deposition methods involve plasma spraying, atmospheric plasma, and suspension plasma techniques. The research focuses heavily on failure mechanisms such as hot corrosion, CMAS (calcia magnesia alumino silicate) attack, thermal shock, and oxidation behavior. Applications are primarily in gas turbine blades, diesel engines, and aerospace superalloys, with significant attention to bond coat design, microstructural stability, and thermal conductivity management.
The largest share of the community's output is found in zirconium research, accounting for 2.1% of all zirconium papers, and yttrium research, accounting for 2.7% of all yttrium papers. Zirconium also contributes the highest raw paper count within this group, with 3,551 papers.
The community comprises 26,047 papers, published most frequently in Surface and Coatings Technology, Ceramics International, and the Journal of Thermal Spray Technology.
Recent work includes non-destructive evaluation of coating defects using electromagnetic and thermographic signals, the development of CMAS-resistant bilayer apatite structures, and the application of high-entropy rare-earth oxide ceramics for next-generation thermal and environmental barrier protection.
