Abstract
A method of fabricating or reparing a blisk () that comprises a plurality of blades () attached to the outer periphery of a disc (). Blades () are formed separately from the disc () and are attached to stubs () on the disc () by friction welding. A metal powder, such as titanium, is sprayed onto the stubs () to reinforce them during the friction welding process. Once the stub () has been coated with the powder spray, plates () are fastened on the disc () between which the sprayed coating () is clamped. The plates () restrain the sprayed coating () to prevent delamination during friction welding. Once each of the blades () has been welded onto the respective stubs () the clamping plates () are removed and the sprayed coating () is machined away.
