COATING METHOD, COATING FILM, AND TURBINE SHROUD
Provided is a coating method, a coating film, and a turbine shroud. The present invention includes: a slurry deposition step of depositing a slurry containing a coarsely particulate ceramic and a finely particulate ceramic on a base material (32) constituted from an oxide-based CMC in such a way that the proportion of coarse particles decreases towards the surface side; a bond coating formation step of heat treating the base material (32) on which the slurry is deposited so as to form a bond coating (33); and a top coating formation step of thermally spraying a ceramic onto the bond coating (33) so as to form a top coating (34).
