Abstract (en)
[origin: WO2022248789A1] The invention relates to a method for manufacturing an abradable layer and a substrate coated with this layer, comprising the following steps: preparing a powder composition (30) comprising at least ceramic particles and an inorganic filler having a lamellar crystallographic structure, the volume content of the inorganic filler in the powder composition being between 1 and 75%; compressing the powder composition (30); and sintering the powder composition (30) thus compressed in order to obtain the abradable layer (12).
