Abstract (en)
[origin: WO2020002799A1] The invention relates to a method for manufacturing an abradable layer (12), which comprises the following steps: - compressing a powder composition (30) comprising at least micrometric ceramic particles having a number average shape factor no lower than 3, the mass concentration of said micrometric ceramic particles in the powder composition being no lower than 85%; and - sintering the powder composition thus compressed in order to obtain the abradable layer.
