Electron Beam-Physical Vapor Deposition
The distribution of the residual stress in the thermal barrier coating, which was made by an electron beam-physical vapor deposition (EB-PVD) method, was determined using X-ray stress measurements. As the bond coating, NiCoCrAIY was low-pressure plasma sprayed on the substrate of austenitic stainless steel. The 8 mass% Y2O3-ZrO2 was coated on the bond coating using the EB-PVD method as the top coating. The top coating had the preferred orientation with the <111> axis direction perpendicular to the coating plane. The distribution of the in-plane residual stress in the top coating was measured using laboratory X-rays. The value of the in plane stresses was determined by the sin^2 ψ method after the separation of the 133 and 331 diffractions. The distribution of the out-of-plane strain in the top coating was measured using the strain scanning method with hard synchrotron X-rays. The out-of-plane strain was obtained from the 333 diffraction which had strong intensity due to the preferred orientation. The measured value of the in-plane stress in the top coating was a large compression, and steeply decreased near the interface between the top and the bond coating. The distribution of the out-of-plane stress showed a compression, and its magnitude was smaller than that of the in-plane stress.
