Abstract
Porcelain enamel coatings give substantial amounts of damping at temperatures between 400-800 C depending on the particular enamel. Suitably chosen enamels can reduce the vibration amplitude at elevated temperatures and increase the fatigue life at all temperatures for those structures subject to forced vibration at resonance. Particularly suitable applications are gas turbine blades, combustion chambers, and aerodynamically heated plates and shells.
