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.

Lubricating Properties

Abstract The results have been presented of an experimental study of the tribological behavior of diamond-like carbon coatings (DLC) doped with chromium and molybdenum obtained by reactive magnetron sputtering. The effect of alloying with these metals on the tribological characteristics of boundary lubrication of a DLC coating/steel contact has been studied for the case of three model lubricants (inactive, surfactant, and chemically active). It has been shown that doping with chromium and molybdenum improves both the tribological characteristics of coatings under dry friction and the lubricating properties of the model oils, while alloying with molybdenum provides lower coefficients of friction and less wear at dry and boundary friction than alloying with chromium.

Thick Coatings

Ti-doped diamond-like carbon(Ti-DLC) coatings and undoped diamond-like carbon(DLC) coatings were synthesized by unbalanced magnetron sputtering using carburized Chromium Molybdenum Steels (SCM415) as substrates. Nanocomposite structure coatings with metal carbides nanocrystals uniformly dispersing in the amorphous carbon matrix were obtained by the optimization of the kinds of doped metals and deposited parameters. This kind of nanocomposite structure permits improved hardness while maintaining a lower residual stress and getting thick coatings. The friction coefficients of Ti doping DLC coatings are relatively lower compared with undoping DLC coatings in engine oil. The analysis on the wear surface of coatings have indicated that: the surface of DLC doped with metal absorbs more elements from the engine oil, which indicates that the doping of metal can improve the affinity of the coating for the engine oil, enhance the formation of lubrication oil films, and reduce the friction coefficient thereby.
