た。2. Description of the Related Art Materials exposed to high temperatures such as gas turbine blades are usually coated with ZrO 2 -based ceramics which have low thermal conductivity, high emissivity and excellent oxidation resistance. The films are roughly classified into the following two types. (1) YSZ (yttria-stabilized zirconia) spray coating:
YSZ (for example, ZrO 2 · 8Y 2 O 3 ) is thermally sprayed on a Co-based or Ni-based heat-resistant superalloy through a MCrAlY (M: Co and / or Ni) alloy layer called a bond coat, and YSZ is a melt. Since it is sprayed in the state, it has a layered structure. (2) YSZ EB / PVD film: Co-based or Ni-based heat-resistant superalloy, MCrAlY called bond coat
A film formed by depositing YSZ by an electron beam heating vacuum vapor deposition method (EB / PVD method) via an (M: Co and / or Ni) alloy layer, and YSZ has a columnar structure. Specific examples of the above-mentioned high temperature exposure material are shown in Table 1, and the compositions of the base material, the intermediate layer (bond coat layer) and the film (top coat layer) are shown in Table 2.

が、未だ実用化されるに至っていない。The above high temperature exposed material is liable to crack due to the difference in thermal expansion coefficient between the base material and the film, which causes peeling. Therefore, in order to relieve the thermal stress between layers, basic research such as a gradient composition method in which the thermal expansion coefficient of the YSZ thermal spray coating is gradually changed in the thickness direction has been conducted.
