Abstract

A method for constructing an abradable coating comprises: a slurry layer formation step Sin which a slurry layeris formed on the surface of a base materialusing a slurry containing ceramic particles and a solvent; a calcination step Sin which the slurry layerformed on the surface of the base materialis sintered and a sintered layerto be a portion of an abradable coating layeris formed; and a slurry removal step Sin which extraneous slurry is removed after the abradable coating layerhas been formed on the surface of the base material, a plurality of the sintered layershaving been laminated in the abradable coating layerthrough a plurality of repeated cycles of the slurry layer formation step Sand the calcination step S
