    摘要： A method is provided for refurbishing a service operated metallic coating on a substrate alloy, the coating including at least within a coating outer surface at least one oxide chemically grown from at least one coating element, for example Al, and chemically bonded with the coating outer surface as a result of thermal exposure during service operation. Growth of the oxide has depleted at least a portion of the coating element from the coating. The method comprises removing the oxide from the coating outer surface while substantially retaining the metallic coating, thereby exposing in the coating outer surface at least one surface void that had been occupied by the oxide. The retained metallic coating is mechanically worked, substantially without removal of the retained coating, to close the void, providing a treated metallic coating surface over which a refurbishing coating is applied. In one form, the mechanical working provides, concurrently, a compressive stress in the substrate alloy beneath the metallic coating.

    摘要： A method is provided for refurbishing a service operated metallic coating on a substrate alloy, the coating including at least within a coating outer surface at least one oxide chemically grown from at least one coating element, for example Al, and chemically bonded with the coating outer surface as a result of thermal exposure during service operation.

The method comprises removing the oxide from the coating outer surface while substantially retaining the metallic coating, thereby exposing in the coating outer surface at least one surface void that had been occupied by the oxide.

    摘要： A method is provided for repairing an article having a fissure in a metallic overlay environmental resistant coating that includes the element Al, for example an overlay coating of the MCrAlY type. The method depletes more than about 90 wt. % of the Al from an exposed coating surface within the fissure and from a coating outer surface adjacent the fissure, to a depth of at least about 7 mils, without removal of the coating and while substantially maintaining the coating thickness. Thereafter, the fissure is repaired.

    摘要： A method is described, for treating a superalloy substrate which includes at least one cavity containing adherent metal oxide material on its surface. A short-pulsed, high repetition rate laser beam is directed against the cavity surface for a period of time sufficient to remove substantially all of the adherent metal oxide material. The laser beam is characterized by a peak power density in the range of about 10 megawatts/cm2 to about 10 gigawatts/cm2. In another embodiment, a high-power, short-pulsed, high repetition rate laser beam is directed to a region on the substrate which includes the cavity, under laser operational conditions which are capable of cutting into the superalloy material; so that a boundary region is formed within the substrate, which encloses the cavity. The cavity can be a crack in a turbine blade, and the crack can be repaired after treatment, by welding, or by another suitable technique.
