  • Publication number: 20200318227
    Abstract: A method for treating a substrate prior to metallic coating includes the steps of providing a substrate having a surface to be coated and at least one contaminant selected from as-delivered organics and post-burn out oxides on the surface; treating the surface with a laser to remove the at least one contaminant to produce a cleaned surface on the substrate; and applying a metallic coating to the cleaned surface. Grit blasting can be avoided, and reverse arc transfer cleaning is avoided or minimized, resulting in time savings and less stress on the substrate.

  • Patent number: 10759004
    Abstract: A method of removing scale from a casting may include positioning the casting relative to a laser emitter. The casting may comprise a superalloy and the scale may have formed on the surfaces thereof, with the scale being a byproduct of a method of manufacturing the casting. The method may also include passing a laser beam emitted from the laser emitter across the casting such that the laser beam causes the scale to at least one of crack, break, shatter, and spall. The superalloy may be a nickel-based superalloy and the scale may include a metal carbide layer.
