  • Patent number: 9932237
    Abstract: Embodiments of a device, or a component of a device, including a stabilized graphite surface, methods of stabilizing graphite surfaces, and uses for the devices or components are disclosed. The device or component includes a surface comprising graphite, and a plurality of haloaryl ions and/or haloalkyl ions bound to at least a portion of the graphite. The ions may be perhaloaryl ions and/or perhaloalkyl ions. In certain embodiments, the ions are perfluorobenzenesulfonate anions. Embodiments of the device or component including stabilized graphite surfaces may maintain a steady-state oxidation or reduction surface current density after being exposed to continuous oxidation conditions for a period of at least 1-100 hours. The device or component is prepared by exposing a graphite-containing surface to an acidic aqueous solution of the ions under oxidizing conditions. The device or component can be exposed in situ to the solution.

  • Patent number: 9889459
    Abstract: An apparatus and method of preparing and coating a large structure such as a ship's hull while in a dry dock wherein a plurality of spray guns disposed in an array are positioned by a robotic arm in a spaced relationship along the surface to be treated so that their spray patterns overlap. The array of spray guns is traversed downwardly and thus painting a strip whereupon the spray guns are secured, move horizontally and then are activated to be moved upwardly until another strip adjacent to and overlapping the first strip is painted. These steps are repeated until the surface area is substantially entirely painted. A shroud is provided for collecting paint oversprays and other excess paint is mounted in the array assemblage. An auxiliary spray gun may be positioned and its spray pattern adjusted to apply paint to area which were missed by the original spray pattern emanating from the array of spray guns.
