In order to examine the fundamental boundary lubrication properties of ceramics, reciprocating friction experiments of silicon based ceramics such as silicon carbide and silicon nitride were conducted with trialkyl phosphites and other oil additives. When ceramics were slid against ceramics, trialkyl phosphites with long carbon chains reduced the friction of silicon nitride markedly; the friction coefficients decreased with an increase in the carbon chain length. Other oil additives, however, did not greatly affect the friction. When ceramics were slid against metals, additives containing chlorine or sulfur increased friction of certain sliding couples. On the other hand, a trialkyl phosphite reduced friction and the friction coefficients increased with an increase in the maximum Hertzian contact pressure.

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.
