    摘要： 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.

    摘要： A mechanical part provided with an amorphous carbon coating (with at least 70 wt. % of carbon not including hydrogen) and used to cooperate slidingly with an antagonistic part having a surface hardness which is a maximum of two thirds of that of the coating. The mechanical part is such that the coating has a roughness Ra which, measured by profilometry, is equal to a maximum of 0.050 microns and, measured by atomic force microscopy, a micro-roughness which is equal to a minimum of 0.004 microns and a maximum of 0.009 microns. This minimizes the wear of the less hard antagonistic part and that of the coating.
