The prepped surface can then be coated using the same or substantially similar coating particle. This method can be used with a continuous airjet, a forced pulsed airjet, a continuous waterjet or a forced pulsed waterjet as the carrier stream. This invention solves the problem of foreign blasting particles becoming embedded in the atomic matrix of the surface to be prepped, which can result in unpredictable behaviour of the surface properties and even catastrophic failure.

  • Publication number: 20110171394
    Abstract: A method of making a combustion turbine component includes thermal spraying a transient liquid phase (TLP) forming layer onto a combustion turbine component substrate and thermal spraying a main material layer onto the TLP forming layer. The combustion turbine component substrate, TLP forming layer, and main material layer are heat treated to thereby bond the main material layer to the combustion turbine component substrate.

  • Patent number: 7964247
    Abstract: A process for the manufacture of sputtering target comprises the steps of i) providing a substrate; ii) plasma melting of a material selected to form the sputtering target, yielding droplets of molten material; and iii) deposition of the droplets onto the substrate, yielding a sputtering target comprised of the coated layer of the material on the substrate. In some application, it might be preferable that the substrate be a temporary substrate and iv) to join the coated temporary target via its coated layer to a permanent target backing material; and v) to remove the temporary substrate, yielding a sputtering target comprised of the coated layer of the material on the permanent target backing material. The plasma deposition step is carried out at atmospheric pressure or under soft vacuum conditions using, for example, d.c. plasma spraying, d.c. transferred arc deposition or induction plasma spraying. The process is simple and does not require subsequent operation on the resulting target.
