Zirconia was coated as the top coating by the electron beam-physical vapor deposition (EB-PVD) method. In the EB-PVD process, the specimens were kept at 1223K and rotated with 5rpm, 10rpm and 20rpm. According to the microscopic observation and the result of the pole figures, the top coalings had a columnar structure, which was made by the piling up of (111) planes. The cross section of the column had a diamond shape, and its diagonal was parallel to the rotation axis. The residual stress on the surface of the top coatings was evaluated by the X-ray diffraction method. Each diffraction profile was separated into the 133 and the 331peak, and the residual stress was measured by the sin^2Ψ method. The measured residual stresses were-76.7MPa for 5rpm, -63.0MPa for 10rpm and -25.1MPa for 20rpm.}, pages = {588--593}, title = {EB-PVDによる遮熱コーティングの残留応力のX線評価}, volume = {56}, year = {2007} }
