    Abstract: Articles including durable and icephobic polymeric coatings are disclosed. The polymeric coatings include a bonding layer which may contain a substantially fully cured polymeric resin providing excellent adhesion to metallic or polymer substrates. The polymeric coating further includes an outer surface layer which is smooth, hydrophobic and icephobic and, in addition to a substantially fully cured resin, contains silicone comprising additives near the exposed outer surface. The anisotropic polymeric coatings are particularly suited for strong and lightweight parts required in aerospace, automotive and sporting goods applications. A process for making the articles is disclosed as well.

    Abstract: Sacrificial inserts for use in gas turbine engines to reduce friction and wear damage between compressor fan blades and the fan rotors are disclosed. The consumable metallic shims have low friction and reduce fretting and galling on fan blade roots and fan rotor dovetail slots thereby increasing their operating lives, as well as reduce engine noise and improve engine efficiency. The electroformed, compliant, multi-purpose shims may have variable thickness and, when positioned between the blade dovetail root and the rotor disk dovetail slot, prevent movement and slippage between air foil blades and the rotor.

    Abstract: Se describen conectores y tomas de corriente positivas de aleacion de plomo y plomo recristalizado, tales como bandas y argollas que se usan, por ejemplo, en baterias acidas de plomo y anodos de extraccion electrolitica, que tienen un porcentaje incrementado de contorno de grano especiales en al menos un parte de la microestructura, que ha sido proporcionada por un proceso que comprende (i) laminado en caliente o frio, o extrusion en caliente o frio o (ii) las etapas para deformar el plomo o aleacion de plomo, y posteriormente recocer el plomo o la aleacion del plomo. Puede proporcionarse tanto un ciclo simple de trabajo y recocido, o puede proporcionarse una pluralidad de tales ciclos. La cantidad de deformacion, el tiempo y temperatura de recristalizacion y el numero de repeticiones de tales etapas se seleccionan para asegurar que un incremento sustancial en la poblacion de contornos de grano especiales se proporcione en la mircroestructura, para mejorar la resistencia a la deformacion progresiva, la corrosion intergranular y el craqueo intergranular de las tomas de corriente y conectores durante el servicio de la bateria, que da como resultado una vida prolongada de la bateria y la oportunidad de reducir el tamano y el peso de la bateria.

    Abstract: An apparatus and system for in-situ electropolishing and/or for in-situ electroforming a structural or functional reinforcement layer such as a sleeve of a selected metallic material on the internal surfaces of metallic tubular conduits are described. The apparatus and system can be employed on straight tubes, tube joints to different diameter tubes or face plates, tube elbows and other complex shapes encountered in piping systems. The apparatus includes components which can be independently manipulated and assembled on or near a degraded site and, after secured in place, form an electrolytic cell within the workpiece. The apparatus contains counter-electrodes which can be moved relative to the workpiece surface during the electroplating and/or electropolishing operation to provide flexibility in selecting and employing electropolishing process parameters and electroplating process parameters to design and optimize the surface roughness as well as the size, shape and properties of the electrodeposited reinforcing layer(s).
