Abstract
Shroud assembly of an axial turbomachine () having a rotor (), such as a turbomachine compressor air-intake shroud (). The assembly comprises an annular layer () of abradable material that is able to cooperate by abrasion with lips () of the turbomachine in order to ensure tightness, and a heating module () for the abradable layer (). The module () comprises electrical heating resistors () within the abradable material in order to prevent the presence of ice on the shroud (). The abradable material is thus used as a heating body which receives, transports and distributes the heat used for de-icing.
