Shroud ring of an axial turbomachine compressor

摘要

The shroud has an annular or cylinder support (34) with a circular internal surface, and a ring (36) with an external face that is opposite to an internal face of the ring. An abradable material layer (22) is formed on the internal surface of the ring, where the ring is made of metallic material. The ring has series of perforations whose diameter is less than or equal to 0.6 mm. A glue layer (38) is formed between the support and the ring, where the support is made of organic material. The abradable material layer has aluminum silicon based polyester type abradable projected by plasma. Independent claims are also included for the following: (1) a compressor of an axial turbine engine, comprising a rotor (2) a method for fabricating a shroud of an axial turbine engine.
