Abstract
The invention relates to a method for manufacturing a turbine shroud () for a turbomachine, the method comprising manufacturing at least one turbine shroud sector (), positioning the turbine shroud sector () 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 () of the turbine shroud sector (). Thereafter, a top mold is positioned on the powder layer and an abradable layer () is made by subjecting the powder layer to a method of SPS sintering, the abradable layer () being for being disposed facing a turbine wheel.
