Abstract

Use of the stator blade platforms for the deposition of a track of adjacent abradable material inside an external turbomachine shell is disclosed. The stator blades are attached to the shell so as to define an annular edge that is substantially continuous and the abradable material is deposited using this edge to delimit a boundary of the track of abradable material.
