    Abstract: A process for in situ electroforming a structural reinforcing layer of selected metallic material for repairing an external surface area of a degraded section of metallic workpieces, especially of tubes and tube sections, is described. Preferably, the metal layer coatings are made of fine-grained metals, metal alloys or metal matrix composites. The plating system can be used on straight tubes, tube joints to different diameter tubes or face plates, tube elbows and other complex shapes encountered in piping systems. A suitable apparatus is assembled on or near the degraded site and is sealed in place to form the plating cell. Also described is a process for plating "patches" onto degraded areas by selective plating including brush plating.

    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: 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).
