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.

Magnetron sputtered non-hydrogenated diamond-like carbon (DLC) coatings were tested against Al, Cu and Ti pins using a vacuum pin-on-disc tribometer. The objective was to compare Al, Ti, and Cu transfer to DLC coatings in air (29% RH) and an inert atmosphere (argon). In argon, a significant amount of adhesion and material transfer occurred from the Al and Ti pins to the DLC coating surfaces inflicting severe damage to the coatings. Wear and material transfer of the DLC coating against Cu were negligible in argon. Compared to tests in argon, the tribological performance of the DLC coatings against Al and Ti improved significantly in ambient air. In contrast, the wear rate of the DLC coatings against Cu was much higher in ambient air compared to that in argon.

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.
