Method of protecting a vibration damping coating from foreign object damage

摘要

A metal is used as a predominant component of an outermost metallic portion (10) of a ceramic-containing (8) and metal-containing (10) vibration damping coating (8,10) for a metallic article (2), for the purpose of enhancing resistance of the coating (8,10) to foreign object damage and/or erosion while substantially maintaining or enhancing vibration damping performance of the coating (8,10). The outermost metallic portion (10) is preferably substantially free of non-metallic intrusions and cavities.
