Abstract:
1. A textured surface comprising: (a) a surface with textured features, (b) wherein the features are adapted to enhance the effectiveness of a nano-particle lubricant, and wherein the features are formed by one or more processes selected from the group consisting of etching, chemical etching, chemical functionalization, laser etching, laser blasting, sand blasting, physical etching, mechanical etching, top down processes, bottom up processes, chemical texturing, physical texturing, mechanical texturing, stamping, laser texturing, vapor deposition, plasma deposition, electroplating, self assembly, directed assembly, subtractive manufacturing, additive manufacturing, hybrid manufacturing, and other deposition, (c) wherein the textured features comprise at least one feature selected from the group consisting of pores, waves, striations, channels, protrusions, asperities, depressions, grooves, holes, low points, high points, cracks, low areas, high areas, exposed sandwiched layers, and chemically functional material, (d) a nano-particle lubricant in contact with the textured features of the textured surface in a position to lubricate the surface, (e) wherein the nano-particle lubricant comprises at least one member selected from the group consisting of: (f) a tribo-film in contact with the textured features of the textured surface in a position to lubricate the surface, the tribo-film comprising at least one of a phosphorus-containing compound, a phosphide, a boron-containing compound, and a boride, (g) wherein the tribo-film comprises at least a component of the nano-particle lubricant, (h) wherein the size of one or more of the textured features is a multiple of the size of a unit of the nano-particle lubricant, and (i) wherein the surface comprises a substrate with a layer of material deposited over the substrate, and wherein the textured features expose parts of the substrate.
