Abstract
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.
