Abstract:
A turbine of a gas turbine engine comprising a stator sealing ring element arranged so as to form a labyrinth sealing joint in combination with at least one wiper, rotatable about the axis of the sealing ring. The element includes an abradable material layer with a surface portion engageable with said movable wiper. The abradable material layer on the surface portion axially includes a first area having a first wiper penetration resistance, said first area corresponding to the axial position of the wiper during nominal operation of the turbine, and a second area adjacent to the first area) and having lower wiper penetration resistance than the first area. The second area is located downstream from the first area and corresponds to the axial position that the wiper takes when a flame goes out in the combustion chamber of the engine.

Claim (Index 3):
The turbine according to  claim 1 , wherein the radius of said surface portion is constant along the two zones, and wherein in said second zone, adjacent to the first, the thickness of the abradable layer is reduced relative to the first zone.
