ABSTRACT:
A compressor blade (30) comprises a vibration damping coating (54) on a first surface of at least one portion of an erosion resistant material (56). The vibration damping coating (54) comprises a plurality of segments (58). The portion of erosion resistant material (56) and the vibration damping coating (54) are adhesively bonded to the compressor blade (30) such that the vibration damping coating (54) is arranged between the surface (50) of the compressor blade (30) and the portion of erosion resistant material (56).
