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.

The Coefficient Of Friction

AbstractMolybdenum dialkyldithiocarbamate (MoDTC) is widely used as a friction modifier in engine lubricating oil. Under MoDTC lubrication, the friction and wear behaviors of tungsten-doped diamond-like carbon (W-DLC) films annealed at 100–400 °C were discussed and evaluated using scanning electron microscopy (SEM), atomic force microscopy (AFM), and Raman spectroscopy. Under (polymerized alpha olefin) PAO + MoDTC lubrication, the coefficient of friction of all samples decreased, but the wear rates of the W-DLC films annealed at 300 °C increased significantly. By interacting with zinc dialkyldithiophosphate (ZDDP), the wear rates of W-DLC films annealed at different temperatures declined significantly owing to the formation of dense phosphate tribofilms on the worn surfaces.
