  • Publication number: 20100000468
    Abstract: A method and masking assembly for masking a dovetail portion of a turbine blade during coating of an airfoil portion of the blade. The masking assembly comprises at least two masking members, each having an exterior surface and an oppositely-disposed undulatory surface complementary to one of oppositely-disposed undulatory surfaces of the dovetail portion. By mating the masking members, the undulatory surfaces thereof define an interior cavity within the masking assembly that accommodates the dovetail portion, and the undulatory surfaces of the masking members contact the undulatory surfaces of the dovetail portion to entrap the dovetail portion within the interior cavity of the masking assembly.

  • Publication number: 20080138533
    Abstract: A process for forming a coating on a surface of a substrate, in which the heating source for the coating process is microwave radiation so that heating of the coating material is selective and sufficient to melt and bond the coating material to the substrate without excessively heating the substrate. The process entails forming a coating material containing powder particles that are sufficiently small to be highly susceptible to microwave radiation. The coating material is applied to a surface of the substrate and subjected to microwave radiation so that the powder particles within the coating material couple with the microwave radiation and sufficiently melt to form a coating on the substrate surface. The microwave radiation is then interrupted to allow the coating to cool, solidify, and mechanically bond to the substrate.

  • Patent number: 7056555
    Abstract: An article having an internal passage therein and an internal article surface is coated by providing a coating slurry that is a mixture of a deposition source including a source of aluminum, a halide activator, and a flowable carrier comprising a flowable compound selected from the group consisting of a flowable organic compound and a flowable inorganic compound. There is no oxide dispersant in the coating slurry. The coating slurry is introduced into the internal passage and dried to remove at least a portion of the carrier therefrom and leave a dried coating material. The article surface in gaseous communication with the dried coating material is heated to form an aluminum-containing coating bonded to the article surface. Any residual dried coating material is removed by blowing compressed air through the internal passage.

  • Publication number: 20050177323
    Abstract: A method of evaluating a gravity-type flow conveyance system is disclosed. The method includes the steps of identifying, quantifying and totaling all upstream inflow sources to compute an anticipated flow at a plurality of access points in the system. The actual depth of flow at each access point is then measured and converted to a theoretical flow for each access point. The anticipated flow and the theoretical flow are then compared to determine whether any restrictions on flow might exist in the system and also to prioritize further inspection and repair of the system.

  • Patent number: 6485792
    Abstract: A method for applying substantially stoichiometric NiAl to the surface of a superalloy substrate. These coatings are applied to substrates subjected to high temperatures and thermal cycling by providing a powder of the substantially stoichiometric material with the desired minor additions of rare earth elements, Cr or Zr. The coatings are applied by a thermal spray process utilizing hydrogen as a fuel while generating a highly reducing flame. The thermal spray method melts the powder and directs it onto the surface of the turbine component that is to be coated. The powder size is carefully controlled to prevent oxidation of the powder while providing a controlled surface finish. The surface roughness of the bond coat is further mechanically worked to a predetermined surface finish prior to application of the ceramic thermal barrier layer by a PVD method.
