Abstract:
A method for constructing an abradable coating comprises: a slurry layer formation step S2 in which a slurry layer 31 is formed on the surface of a base material 30 using a slurry containing ceramic particles and a solvent; a calcination step S3 in which the slurry layer 31 formed on the surface of the base material 30 is sintered and a sintered layer 35 to be a portion of an abradable coating layer 22 is formed; and a slurry removal step S5 in which extraneous slurry is removed after the abradable coating layer 22 has been formed on the surface of the base material 30, a plurality of the sintered layers 35 having been laminated in the abradable coating layer 22 through a plurality of repeated cycles of the slurry layer formation step S2 and the calcination step S3.
