Abstract: A method of forming a lubricant coating, a method of coating a bearing surface with a lubricant coating, and a vehicle including a bearing including a lubricant coating. A substrate, such as a bearing, including a surface and an electrode are immersed in an electrolyte bath. The electrolyte bath includes an aqueous electrolyte solution including sodium metabisulfite (Na2S2O5), sodium molybdate (Na2MoO4·2H2O), a pH modifier, an anionic surfactant, and water. A first pulsed direct current is applied through the aqueous electrolyte solution using a direct current power supply and a molybdenum disulfide (MoS2) layer is formed on the surface of the substrate.

Abstract: A coating system is disclosed. The coating system includes a coating disposed on a substrate and a plurality of functionalized particles within the coating. The plurality of functionalized particles is configured to dissipate localized thermal flux from the substrate, where at least a portion of the plurality of functionalized particles are aligned.
