    Abstract: Articles including anisotropic electrodeposited layers of fine-grained alloys of Co, Cu, Fe, Ni and/or Zn with minor additions of B, O, P and S that provide high strength, ductility and heat-resistance, are disclosed as well as a process for making the articles. Non-metallic additions of ≤2% are required to significantly increase the maximum temperature at which softening and grain-growth occurs. Electrodeposition conditions in a single plating cell are adjusted and/or modulated to vary at least one property in the deposit direction and/or along the length and/or width of the workpiece once, constantly or repeatedly, to form a graded and/or layered electrodeposit. Variable property metallic material deposits containing, at least in part, a fine-grained microstructure and variable property in the deposit direction and optionally multi-dimensionally, provide superior overall mechanical properties and temperature stability. Various methods and electroplating apparatuses and approaches to practice the invention are also provided.

    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: 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).

    Abstract: A method for electrodepositing a coating/free-standing layer on a workpiece in an electrolytic cell includes moving the workpiece and an anode applicator tool having a consumable anode insert relative to each other; anodically dissolving a metal from the insert and cathodically depositing the metal on the workpiece; providing flow of electrolyte solution through the insert to ensure that greater than 90% of the anodic reaction is represented by dissolution of the metal; recirculating collected electrolyte solution exiting the electrolytic cell through the insert; applying an electric current to the electrolytic cell; maintaining a concentration of the anodically dissolved metal within ±25% of each Ampere-hour per liter of electroplating solution; and creating a cathodic electrodeposit on the workpiece which includes the anodically dissolved metal, the chemical composition of the deposit varying by less than 25% in the deposition direction over a selected thickness of up to 25 microns of the deposit.

    Abstract: Grain-refined and amorphous metallic material based friction liners for braking devices as used, e.g., in motor vehicles such as cars, trucks, motorcycles, as well as bicycles and other applications requiring, at least at times, means for decelerating rotating parts are disclosed. Friction liners can have isotropic or anisotropic properties and the friction surfaces can optionally be rendered hydrophobic.
