Abstract

We have studied the mechanical damping and elastic stiffness of ceramic coatings, of yttiria-stablized zirconia, deposited by air plasma spraying (APS) or electron-beam physical-vapor-deposition (EB-PVD) on Inconel beams. The loss factor and Young's modulus of the coating have been estimated as a function of strain amplitude with the aid of a numerical analysis. It has been found that the coating produced by APS has higher damping, lower elastic stiffness and stronger amplitude dependence than that produced by EB-PVD. These features are correlated with the microstructure examined by scanning electron microscopy.
