Embodiments of the present invention may provide textured surfaces to be lubricated, the texturing to enhance the effectiveness of the intended nano-lubrication. The texturing may make asperities and depressions in the surface to be lubricated. This texturing may be executed, for example, by chemical etching, laser etching, or other techniques. This texturing may create locations in the lubricated surface to hold or anchor the intended nano-lubricants, to facilitate the creation of a tribo-film on the surface when the lubricated surface is used under pressure, and resulting in delivery of multiple chemistries from the nano-lubricant.
