Abstract: Systems and methods for applying a coating to an interior surface of a conduit. In one embodiment, a spray gun configured to apply a coating is attached to an extension arm which may be inserted into the bore of a pipe. The spray gun may be a thermal spray gun adapted to apply a powder coating. An evacuation system may be used to provide a volume area of reduced air pressure for drawing overspray out of the pipe interior during coating. The extension arm as well as the spray gun may be cooled to maintain a consistent temperature in the system, allowing for more consistent coating.

Abstract: A method for forming a thermal barrier coating system on an article subjected to a hostile thermal environment, such as the hot gas path components of a gas turbine engine. The coating system is generally comprised of a ceramic layer and an environmentally resistant beta phase nickel aluminum intermetallic (null-NiAl) bond coat that adheres the ceramic layer to the component surface. A thin aluminum oxide scale forms on the surface of the null-NiAl during heat treatment. An additional layer of diffusion aluminide may can be formed underlying the ceramic layer. The null-NiAl may contain alloying elements in addition to nickel and aluminum in order to increase the environmental resistance of the null-NiAl. These elements include hafnium, chromium and zirconium and increase the oxidation resistance of the null-NiAl. The null-NiAl is supplied as a powder having a size in the range of 20-80 microns. The null-NiAl powder is applied using air plasma spray techniques to produce a surface having a roughness of 400 microinches or rougher. The ceramic top coat, a stabilized zirconia, typically ytrria-stabilized zirconia, can be applied using inexpensive thermal spray techniques to greater thicknesses than achievable otherwise because of the rough surface finish of the underlying null-NiAl bond coat. Alternatively, the null-NiAl coat can be used as an environmental coating without application of an overlying ceramic topcoat.

Abstract: Spray on polyurethaneurea coatings provide corrosion resistance over long periods of time to marine fixtures, particularly of active metals such as aluminum and steel. Radar arches, fishing platforms, railing systems, etc. can maintain their aesthetics over extended periods of time, even in salt water environments, when the coating has been penetrated to the metal surface.

Abstract: Described herein is a method for providing a clean edge at the interface of a portion of a substrate coated with a coating system and an adjacent portion of the substrate which is uncoated. The method includes the step of forming a zone of non-adherence on the substrate portion which is to be uncoated, prior to application of the coating system. The zone of non-adherence is adjacent the interface, so that the coating system will not adhere to the zone of non-adherence, but will adhere to the portion of the substrate which is to be coated with the coating system.

Abstract: The process according to the invention discloses production of a high-quality insulation for conductors or conductor bundles. In this process, internal corona-discharge protection, insulation and external corona-discharge protection are all applied to the conductor or conductor bundle in successive steps by means of thermal spraying. The application thickness per spraying run is up to 0.2 mm, thus ensuring that the layer is free of defects and therefore avoiding partial discharges. Moreover, the ability to withstand thermal loads is considerably improved by the use of high-temperature plastics with fillers comprising inorganic materials as coating powder.

Abstract: A method and device of treating an irregularly shaped article to prepare the article for painting is provided. The device includes a burner which can produce an adjustable flame tongue which can fit into crevices, openings and other irregular topographical features of an item to be painted or otherwise coated. The burner device further provides means to apply a grafting chemical on a freshly oxidized surface. Further, the invention provides means to colorize treated objects so that they may be recognized as having been treated. In another embodiment, the grafting chemicals may be enhanced with electrolytic solutions such that electrostatic methods of painting may be subsequently employed on the item. In an alternate embodiment, the burner is adapted to spray a powder inside of a generally enclosed flame, and is used in conjunction with chop guns to manufacture glass or carbon fiber preforms.

Abstract: A domed enclosure wall for a plasma processing chamber is made from a dielectric material having a roughened surface with a roughness average of from about 150 to about 450 microinches. A plasma sprayed ceramic coating is applied on the roughened surface of the dielectric material. The plasma sprayed coating comprises a textured surface having a roughness with an average skewness that is a negative value. When the enclosure wall is used in a plasma processing chamber, sputtered material generated by a plasma formed in a plasma processing chamber has good adherence to the textured surface.

Abstract: The invention provides a process for applying a heat shielding coating system on a metallic substrate. The coating system comprises at least three individual layers selected from the group of barrier layer, hot gas corrosion protection layer, protection layer, heat barrier layer, and smoothing layer. The coating system is applied to the metallic substrate by low pressure plasma spraying in a single operation cycle. This process enables the layers to be applied in an arbitrary sequence. The process is preferably used in applying a coating system to a turbine blade, particularly a stator or a rotor blade of a stationary gas turbine or of an aircraft engine, or to another component in a stationary or aircraft turbine that is subjected to hot gas.
