title = "Comparison of the damping and stiffness properties of 8wt% yttria stabilised zirconia ceramic coating deposited by the APS and EB-PVD techniques",
abstract = "Recent research into the use of thermal barrier coatings has shown that they can provide sufficient additional damping, reducing vibration levels and significantly extending the life of the coated component. Various deposition techniques may be employed to apply ceramic coatings with Air Plasma Spraying (APS) and Electron Beam - Physical Vapour Deposition (EB-PVD) being the most widely used. However, one has to take into account that even when the starting ceramic material is the same, the microstructures of the resultant coatings depend strongly on the deposition technique. The objective of this paper is to study of the differences in the damping behaviour and stiffness of an yttria-stabilised zirconia (YSZ with 8%wt yttria) coating deposited by APS and by EB-PVD. Both damping and stiffness of these two YSZ coatings were estimated from tests performed at room and high temperatures. Moreover, this paper presents the microstructural characterisation of these two YSZ coatings using scanning electron microscopy, and attempts a correlation of the differences in their properties to their microstructure.",
