Abstract: The present disclosure provide for coatings, coated structures, methods of coating, methods of coating a structure, and the like. In an aspect, the coating is a tribocatalytically-active coating, where the tribocatalytically-active coating interacts with the hydrocarbon environment forming a protective carbon-based tribofilm on the surface of the coating, which can be actively formed (reformed) during use of the coated structure within the hydrocarbon environment.

Abstract: A coated article includes a substrate, and a coating disposed on a surface of the substrate. The coating comprises a transition metal dichalcogenide (TMD). A method of forming a coating includes dispersing a transition metal dichalcogenide (TMD) and optionally tungsten carbide in a solvent to form a mixture, spraying the mixture on a surface of a substrate, evaporating the solvent, and forming a coating on the substrate comprising the TMD.
