Estimating the term…
A coating system and coating method for damping vibration in an airfoil of a rotating component of a turbomachine. The coating system includes a metallic coating on a surface of the airfoil, and a ceramic coating overlying the metallic coating. The metallic coating contains metallic particles dispersed in a matrix having a metallic and/or intermetallic composition. The metallic particles are more ductile than the matrix, and have a composition containing silver and optionally tin. The method involves ion plasma cleaning the surface of the airfoil before depositing the metallic coating and then the ceramic coating.
A method for providing a coating system on an airfoil of a rotating component of a turbomachine, the method comprising the steps of:
A method for providing a coating system on an airfoil of a rotating component of a turbomachine, the method comprising depositing the coating system on a surface of the airfoil so that the coating system comprises a metallic coating and a ceramic coating, wherein:
