As the X-ray energy becomes higher, the penetration depth gets deeper. The in-plane stress, \u03c3_1, is measured by the conventional X-ray with the low energy, and the out-of-plane stress, \u03c3_1-\u03c3_3, is measured by the synchrotron X-ray with high energy. The spalling stress, \u03c3_3, can be estimated from two measurements obtained by the conventional and the synchrotron X-ray methods. The bond coating of NiCoCrAlY with a thickness of 0.2mm was made by plasma spraying on a Ni super-alloy substrate, and the ZrO_2 top coating with a thickness of 0.2mm was plasma sprayed on the bond coating. The distribution of the in-plane residual stresses, \u03c3_1, in the top coating was measured with characteristic X-rays Cr-K\u03b1 by repeating the measurements after successive removal of the surface layer. The residual stresses, \u03c3_1-\u03c3_3, were measured by the synchrotron X-rays with 73 keV. The spalling stress was estimated from the stresses measured by the two methods. The spalling stress, \u03c3_3, was small tensile beneath the surface of the top coat but increased to 75 MPa near the interface between the top and bond coatings. A high tensile stress near the interface may induce the delamination of coatings.", "subitem_description_type": "Abstract"}]}, "item_5_full_name_3": {"attribute_name": "\u8457\u8005\u5225\u540d",
