Coatings
Diesel, gas and turbine engines are being operated at increasingly higher temperatures to improve combustion performance and reduce environmental impact, especially in the aerospace and land-based power industries. To maintain system reliability at these higher temperatures, ceramics protective coatings are part of the design and operation.
Zirconia-based ceramic coatings, usually stabilized with dopants like yttria, have demonstrated superior performance in providing the best combination of thermal insulation, wear, oxidation and corrosion resistance. In addition to their chemical properties, these ceramic thermal barrier coatings are capable of forming the microstructure and porosity necessary to achieve optimum performance.
