ABSTRACT:
A vibration damped turbo-machine blade includes a shot peened metallic substrate which provides a shape for the blade. Carried on the metallic substrate and bonded to an outer surface of this substrate is a singular ceramic coating of a damping material. The substrate may be made of forged titanium, and the coating may be made of a ceramic material including cobalt at a weight percentage of from about 13% to about 21%, with the balance of the ceramic material being substantially all tungsten carbide.
