A method for increasing the coefficient of adhesion between two parts that rotate as one with a rotor, for example a turbomachine rotor, those parts pressing against one another via pressing faces. The method includes milling at least one of the pressing faces so as to modify its surface finish and increase its roughness, then covering the or each machined face with a thin layer of a material that is hard and has a high coefficient of friction.

A method for ultrasound shot-blasting by a cloud of balls set in motion through contact with a sonotrode having one metallic surface including an area of difficult access, characterized in that the surface is that of a hook axially restrained on a turbomachine blade including a groove provided between the hook and the base of the blade, and the cloud of balls is contained in a chamber encompassing the groove and the surface portion outside the groove.
