Surface coatings and surface modifications are an integral part of advanced materials. Surface coatings enhance the material performance by providing protection from extreme environments such as high temperature, high stress, siliceous debris (sand and volcanic ash), oxidizing and corrosive species, and erosive environments. Thermal and environmental barrier coatings are enabling technologies for superalloy and ceramic matrix composite (CMC) components. Tribological coatings improve the life of components in erosive environments. Various coatings are used to improve the functionality of components. This session includes presentations on the processing, materials characterization, and performance of coatings produced by a wide variety of technologies that encompass thermal spray (plasma spray, HVOF, etc.), kinetic based spray processes (cold spray, aerosol deposition, etc.), physical vapor deposition (EB-PVD, PS-PVD, etc.), chemical vapor deposition, and solution-based processes (slurry, sol-gel, etc.). Topics of focus include new innovations in process technology, characterization, non-destructive evaluation, modeling, lifing, and emerging applications. |
