    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.

    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.
