Abstract: Fracture-resistant and self-lubricating wear surfaces are provided. In an implementation, a machine surface that is subject to wear is coated with or is constructed of a metallic nanostructure to resist the wear and to provide fracture-resistant hardness, built-in lubrication, and thermal conductivity for heat-sinking friction. The metallic nanostructured surface may be used, for example, on a face seal, bushing, bearing, thrust member, or hydraulic flow passage of an electric submersible pump. In an implementation, the metallic nanostructured surface is a nanocrystalline alloy including nanograin twins of a body-centered cubic (BCC), face-centered cubic (FCC), or hexagonal closest packed (HCP) metal. The nanostructured alloy may include atoms of copper, silver, gold, iron, nickel, palladium, platinum, rhodium, beryllium, magnesium, titanium, zirconium, or cobalt, and may provide more hardness and lubricity than diamond-like carbon coatings or carbides.

Abstract: A wind turbine rotor comprising a hub (1) from which a plurality of blades (2) project to a radius of at least 50 metres. Each blade comprising a hollow fairing supported by a central spar. Each blade has a thickness t at a radius r; characterised in that when r=0.5 R, t>0.3 T, where R is the radius of the blade and T is the thickness of the blade at the root end. By being thicker for a greater proportion of the blade, the aerodynamic performance of this part of the blade is worse, but this is more than compensated for as it allows better aerodynamic performance where it matters more, namely at the outer part of the blade. It also allows larger blades to be provided.
