摘要:
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.

The fine-grained and/or amorphous metallic coatings are particularly suited for strong and lightweight sporting goods exposed to thermal cycling although the coefficient of linear thermal expansion (CLTE) of the metallic layer and the substrate are mismatched.
摘要:
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, decelerating rotating parts are disclosed. Friction liners can have isotropic or anisotropic properties and the friction surfaces can optionally be rendered hydrophobic.
摘要:
Metal-clad polymer articles containing structural fine-grained and/or amorphous metallic coatings/layers optionally containing solid particulates dispersed therein, are disclosed. The fine-grained and/or amorphous metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, automotive parts and components exposed to thermal cycling although the coefficient of linear thermal expansion (CLTE) of the metallic layer and the substrate are mismatched. The interface between the metallic layer and the polymer is suitably pretreated to withstand thermal cycling without failure.

Corrosion resistant, grain-refined and/or amorphous Ni- and Cu-free Co-bearing coatings on polymer substrates for use in human contact applications, including industrial products, automotive products, medical surgical devices, and medical products, are disclosed.
摘要:
Super-hydrophobic and self-cleaning articles produced by imprinting exposed surfaces with suitable fine-grained and/or amorphous metallic embossing dies to transfer a dual surface structure, including ultra-fine features less than or equal to 100 nm embedded in and overlaying a surface topography with macro-surface structures greater than or equal to 1 micron are disclosed.
摘要:
Free standing articles or articles at least partially coated with substantially porosity free, fine-grained and/or amorphous Co-bearing metallic materials optionally containing solid particulates dispersed therein, are disclosed. The electrodeposited metallic layers and/or patches comprising Co provide, enhance or restore strength, wear and/or lubricity of substrates without reducing the fatigue performance. The fine-grained and/or amorphous metallic coatings comprising Co are particularly suited for articles exposed to thermal cycling, fatigue and other stresses and/or in applications requiring anti-microbial properties.

摘要:
Metal-coated polymer articles containing structural substantially porosity-free, fine-grained and/or amorphous metallic coatings/layers optionally containing solid particulates dispersed therein on polymer substrates, are disclosed. The substantially porosity-free metallic coatings/layers/patches are applied to polymer or polymer composite substrates to provide, enhance or restore vacuum/pressure integrity and fluid sealing functions. Due to the excellent adhesion between the metallic coating and the polymer article satisfactory thermal cycling performance is achieved. The fine-grained and/or amorphous metallic coatings are particularly suited for strong and lightweight articles, precision molds, sporting goods, aerospace and automotive parts and other components exposed to thermal cycling and stress created by erosion and impact damage.
摘要:
Anode applicators include consumable anodes, that can be operated in a non-stationary mode and are insensitive to orientation, are used in selective plating/brush electrodeposition of coatings or free-standing components. The flow-through dimensionally-stable, consumable anodes employed are perforated/porous to provide relatively unimpeded electrolyte flow and operate at low enough electrochemical potentials to provide for anodic metal/alloy dissolution avoiding undesired anodic reactions. The consumable anodes include consumable anode material(s) in high surface area to reduce the local anodic current density. During electroplating, sufficient electrolyte is pumped through the consumable anodes at sufficient flow rates to minimize concentration gradient and/or avoid the generation of chlorine and/or oxygen gas and/or undesired reaction such as the anodic oxidation of P-bearing ions in the electrolyte. The active consumable anode material(s) can have a microstructure which is fine-grained and/or amorphous to ensure a uniform anodic dissolution.
