The given work briefly reports on the history synthesis of new type carbon materials having no analogs in the world, which provides essential reducing of power losses in lubri-cated tribounits. Efficiency of these new carbon materials is based on the established by the authors of the work fact that the carbon coatings with monocrystalline or polycrystalline highly or-dered structures and linear chains of carbon increase essentially the level of molecular or-dering in lubricating boundary layers and ensure adsorption of boundary layers on the coat-ings. Boundary layers repeat highly ordering structure preset by surface of the coating what results in lubricating ability improving, boundary layers thermal stabilization, extending the ranges of operating temperatures of oils, etc. Besides, using the mentioned coatings allows lowering the number of additives in lube oils. Orientation effect of coatings under consideration on molecular ordering in boun-dary lube layers and correspondingly, lubricity improving, which was established early on some model oils, now is demonstrated as applied to commercial lube oils and cut-ting fluids in gyroscopes and extrusion tread instrument. The authors of the this work made a set of many theoretical and experimental studies including synthesis of coatings, analysis of coatings structure, tribological tests of nano-coatings with various oils, etc.
