The given work brief report on the history synthesis of new type nanocomposite with carbon materials having no analogues in the world, which provides essential reducing of power losses in lubricated 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 ordered structures and linear chains of carbon increase essentially the level of molecular ordering in lubricating boundary layers and ensure adsorption of boundary layers on the coatings. Boundary layers repeat highly ordering structure present 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. A new type functional materials of diamond like carbon (DLC) namely nanostructured coating-orientants and PVD process is developed to produce thick (DLC + AlTiN) coating on any metal or ceramic substrates. The new type of the functional materials has no analogues in triboengineering. The findings suggest that the nanocomposite coatings with orientating effect on boundary layers are advantageous for improving antifriction characteristics and for governing processes of boundary lubrication.
