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.

Ash, sand-resistant thermal barrier coatings and novel test rig

By Eileen De Guire / February 21, 2012

Apropos to the latest round of ash clouds spewing from the EyjafjallajökullI volcano, plus indications that some
utilities are going to be building new high-temperature fast-cycle gas turbines for peak electrical power generation, we offer this video that expands on a story I first wrote about in April.
