AXIAL TURBOMACHINE COMPRESSOR OUTER CASING

摘要

The invention relates to a casing, particularly of an axial turbomachine compressor. This casing comprises a support (34) of cylindrical overall shape made of composite material, a metal hoop (36) fitted by bonding to the internal surface of the support (34), and a layer of abradable material (22) fitted by plasma spray onto the internal surface of the metal hoop (36). The metal hoop (36) is preferably made of stainless steel and is preferably perforated. The perforation allows better keying of the adhesive and allows the degassing thereof. The external surface of the metal hoop (36) is preferably sandblasted prior to bonding. Its internal surface is also preferably sandblasted prior to the plasma spraying of the abradable material.
