Abstract
An abradable structure () is provided, with regions () with lower resistance to wearing produced by labyrinth seal lips (), at specific points in the axial direction of the turbomachine, where lip interference could cause the rotor to block up, such as after a temporary shutdown of the turbomachine. These regions may be produced by local weakening () or by the abradable material having a structure that is less dense. Application, for example, to turbomachine turbines.
