environmental barrier coatings
Ytterbium-based silicates are a current generation of environmental barrier coating materials that demonstrate much promise for protecting ceramic matrix composite components in jet engines. Researchers from the University of Manchester examined the effect of thermal ageing on microstructural characteristics and elastic properties of these silicates.

Read MoreMany researchers are working to uncover alternatives to yttria stabilized zirconia for use as environmental barrier coatings. High-entropy oxides are among the classes of materials being explored, and two papers in Journal of the American Ceramic Society explore different high-entropy oxide systems.
Read MoreThermal and environmental barrier coatings are often used to protect turbine blades made from ceramic matrix composites—but these coatings are prone to damage caused by environmental silicate contamination. In three papers published in JACerS, researchers provide extensive insights into the many aspects of damage.
