Abstract
The invention concerns a method of recuperating a turbine element constituted of a substrate, forming the body of the element, and a protective coating adhering to the substrate. The method comprises the control of the turbine element in order to pinpoint the zones having a bonding defect between the protective coating and the substrate, and the elimination of the bonding defects between the protective coating and the substrate. The bonding defects are eliminated by means of a laser beam directed onto each zone having a bonding defect in order to induce a localized melting of the protective coating and the underlying substrate and enable a sound bond, at the level of said zone, between the protective coating and the substrate after stopping the laser beam.
