セラミックス積層体
Document Type and Number:
Japanese Patent JP7035726
Kind Code:
B2
Abstract:
To provide a ceramic laminate having an excellent bonding force between the ceramic coating of the ceramic laminate and a base material.SOLUTION: A ceramic laminate 1 includes a ceramic coating 3 laminated on a base material 2. When an interface (film/base material interface 4) between the ceramic coating 3 and the base material 2 appearing in the cross section of the ceramic laminate 1 is presented by a curve z(x) including a high wave number component and a low wave number component, a wavelength range λof the high wave component is 0.1 μm or more and is equal to or less than the maximum grain size Dof the ceramic coating 3; a wavelength range λof the low wave number component is larger than the maximum Dand is 10 μm or less; the average power spectrum density Pof the high wave number component calculated from the curve z(x) is 2×10μmor more; and the average power spectrum density Pof the low wave number component calculated from the curve z(x) is 0.5×10μmor more.SELECTED DRAWING: Figure 1
