Will it spall? Phase diagrams, thermal expansion, and barrier coating degradation

By Jonathon Foreman / August 11, 2020

Thermal 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.
