A Method to Apply Thermal and Environmental Barrier Coatings

Innovators at NASA's Glenn Research Center have adapted a process to apply thermal and environmental barrier coatings using a unique combination of a plasma spray (PS) process and a physical vapor deposition (PVD) process to improve the coverage and quality of the coatings. Built-up layers that are smooth, thin, strain-tolerant, heat-resistant, and steam-resistant can be generated with this multi-layer system architecture in a one-step coating process.
