A method of repairing a flange of a casing, or a casing made of aluminum, for a turbine engine or an airplane turboprop or turbojet, the flange including at least one through hole for passing a bolt for fastening equipment. The method includes: forming a spot face in the flange around the hole for passing the bolt; anodizing the bottom surface of the spot face; placing a washer on the spot face; and fastening the washer to the flange using adhesive.

Method for repairing a flange of a housing

A method for repairing a compressor blade of a turbine engine, the blade including a cat's tongue at the radial end thereof, the radial extension of which is less than a predefined nominal radial extension. The method includes elongating the cat's tongue via a cold-compacting operation applied to the walls of said tongue, such that the radial elongation thereof becomes greater than the nominal extension. The compacting operation is a rollerburnishing operation carried out by moving the end of the blade between two rollers having rectilinear generatrices and spaced apart by a distance smaller than the thickness of the cat's tongue, along the chord connecting the leading edge with the trailing edge thereof.
