  • Patent number: 7521088
    Abstract: A method and system of applying a corrosion inhibitor to the interior component parts of a turbine to provide corrosion protection to the components is disclosed. The intake and exhaust openings in the turbine are sealed using plastic and/or metal covers to contain the corrosion inhibitor inside the turbine. An air horn connected to an outlet vent in one of the covers induces air into and from the turbine's interior. A fog of corrosion inhibitor is introduced into the turbine through at least one inlet vent in a different cover located diagonally at an opposite end of the turbine. A sprayer is used for introducing the corrosion inhibitor into the inlet vent while the air horn is operating so that the corrosion inhibitor is caused to be drawn into and through the interior of the turbine to coat the interior component parts of the turbine. The corrosion inhibitor is introduced into the inlet vent until the corrosion inhibitor coats all exposed surfaces of the components inside turbine.

  • Patent number: 7521087
    Abstract: A catalyst composition is applied to an interior of a hollow substrate. The composition is coated on the substrate by immersing the substrate into a vessel containing a bath of coating slurry. A vacuum is then applied to the partially immersed substrate. The intensity of the vacuum and its application time is sufficient to draw the coating slurry upwardly from the bath into each of a plurality of channels located in the interior of the hollow substrate. After removing the substrate from the bath, it is rotated 180°. A blast of pressurized air is applied at an intensity and for a time sufficient to distribute the coating slurry within the channels of the substrate to form a uniform coating profile therein.

  • Patent number: 7498056
    Abstract: The method for reconditioning ducts in air conveying or processing networks envisages generating an air flow with maximum turbulence between two openings of the duct sections to be treated. An aerosol is then generated inside the airflow, consisting of a film-forming product with liquid droplets of predetermined average size, in the vicinity of an upstream section of the duct to be treated relative to the direction of movement of the air flow. The droplets containing polymer precursors are deposited on the inner surface of the duct forming a liquid film which, after a crosslinking step, results in the formation of a uniform and continuous solid coating. Measurement data identifying the geometric form of the duct to be treated are converted during a calculation step performed using a model into at least one pair of values for the flowrate and average size of the droplets, respectively.

    Abstract: A bond coat process for thermal barrier coatings. The method includes, after cleaning and masking the external surface of the substrate, first applying a layer of NiCrZr alloy to the external surface of the substrate using a sputter coat or other suitable process. Aluminum is then applied to the substrate, using either a vapor phase aluminization (VPA) or chemical vapor deposition (CVD) process, wherein aluminum diffuses into the NiCrZr alloy layer wherein a diffusion layer is formed by the aluminum with the substrate material on the internal surface of the substrate. The coated substrate may then be subjected to a heat treatment in a protective atmosphere to further allow diffusion of the aluminide into the NiAlCrZr diffusion layer. The substantially Al outer layers of the NiAlCrZr diffusion layer, and the diffusion aluminide layer, will provide an aluminum source for the surface, which will oxidize to form a tightly adherent aluminum scale.

  • Patent number: 6572642
    Abstract: A prosthesis having an apertured structure is located in a chamber (11) which is taken to sub-atmospheric pressure. Once sub-atmospheric pressure has been reached, a liquid, optionally containing pharmacological agents, is introduced into the chamber. Drawn by the sub-atmospheric pressure, the liquid saturates the apertured structure of the prosthesis. In this way, the invention eliminates the risk of air being trapped in the apertured structure that could give rise to the formation of blood clots after implantation of the prosthesis. The liquid can contain drugs that penetrate the prosthesis, performing their therapeutic action locally and over time after implantation.

    Abstract: A method for partially coating a cylindrical carrier body with a coating suspension, the carrier body having a cylindrical axis, two end faces, an envelope, and an axial length L, and being provided with a series of channels extending from the first end face to the second end face. A desired coating quantity of the coating suspension is applied onto the carrier body by vertically aligning the cylindrical axis and introducing the coating suspension into the channels through the lower end face. The carrier body, measured from the lower end face, is filled with a filling volume of the coating suspension which is metered, such that the carrier body is only filled up to a height that amounts to a predetermined fraction of its length L. Subsequently, excess coating suspension is removed downward so that the desired coating quantity remains on the carrier body.
