Abstract

The invention relates to a method for manufacturing a turbine shroud (24) for a turbomachine, the method comprising manufacturing at least one turbine shroud sector (28), positioning the turbine shroud sector (26) in a bottom mold so that an outer surface of the turbine shroud sector is in contact at least in part with the bottom mold, and depositing a powder layer on an inner surface (28) of the turbine shroud sector (26). Thereafter, a top mold is positioned on the powder layer and an abradable layer (32) is made by subjecting the powder layer to a method of SPS sintering, the abradable layer (32) being for being disposed facing a turbine wheel.
