In about a decade, since interest about boundary lubrication properties of diamond-like carbon (DLC) coatings exists, mainly chemical aspects of the DLC lubrication were investigated, i.e. focusing on interactions between various additives and coatings, while physical aspects of coating-oil interactions were not discussed in a greater extent. To elucidate some of these effects, we have analyzed the friction behaviour of DLC coatings and steel under different boundary lubrication conditions by using polyalphaolefin (PAO) base oils having different viscosity grades. Based on this, we have identified several tribo-physical effects in these contacts and for the purposes of this paper we briefly discuss the physical adsorption between the oils and the DLC surfaces, clearly indicating existence of rather strong physically adsorbed layers, which were able to resist high shear stresses under severe boundary lubrication.

В обзоре на основе анализа работ, содержащих результаты экспериментальных исследований, посвященных трибологии граничной смазки поверхностей трения c нанесенными на них алмазоподобными углеродными покрытиями, рассмотрено влияние на трибологические характеристики как особенностей структурного состояния углеродной фазы таких покрытий, так и их легирования. При обсуждении особое внимание уделено методам трибологических испытаний покрытий и эффектам образования защитных слоев, обеспечивающих смазочное действие и состоящих из адсорбированных молекул поверхностно-активных веществ, используемых для улучшения антифрикционных и противоизносных свойств смазочной среды.
