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 are provided. A substrate, such as a bearing, including a surface and an electrode is impregnated in an electrolyte bath. The electrolyte bath comprises an electrolyte aqueous solution, and the electrolyte aqueous solution comprises sodium pyrosulfite (Na2S2O5), sodium molybdate (Na2MoO4. 2H2O), a pH regulator, an anionic surfactant and water. Applying a first pulsed direct current through the aqueous electrolyte solution using a direct current power source, and forming a molybdenum disulfide (MoS2) layer on the surface of the substrate.

    本发明提供了形成润滑剂涂层的方法、用润滑剂涂层涂布轴承表面的方法以及包含包括润滑剂涂层的轴承的车辆。将包括表面和电极的基材(如轴承)浸渍在电解质浴中。所述电解质浴包括电解质水溶液,所述电解质水溶液包括焦亚硫酸钠(Na2S2O5)、钼酸钠(Na2MoO4·2H2O)、pH调节剂、阴离子表面活性剂和水。使用直流电源施加第一脉冲直流电流通过电解质水溶液,以及在基材的表面上形成二硫化钼(MoS2)层。
