Полученные зависимости коэффициента трения µ и длины пробега L образцов до момента разрушения покрытия от тока и индукционных катушек (λ, А) – мощности ионного потока, количества стабилизатора – азота (%N) позволили не только оптимизировать режимы нанесения покрытия, но и выявить недостатки DLC-покрытий. В частности, установлено, что коэффициент трения практически остается постоянным и достаточно малым во всем диапазоне нагрузок на уровне µ = 0,17. Что касается износа, то в интервале значительных нагрузок экспериментальная зависимость пути трения до разрушения непрерывно убывает и стремится к нулю. Поэтому дальнейшие исследования были направлены на разработку технологии получения комбинированного покрытия путем чередования металлокерамических слоев CrAlSiN, полученных дуговым напылением путем физического вакуумного осаждения PVD-покрытий, и углеродных (в том числе алмазоподобных) слоев, полученных лазерным испарением графита, без извлечения образцов-подложек из вакуумной камеры установки BRV-600. В результате совмещения высокой износостойкости нитридного покрытия CrAlSiN и низкого коэффициента трения покрытия DLC существенно увеличивает износостойкость высоконагруженных трибосопряжений.</p></abstract><trans-abstract xml:lang="en"><p>The study considers the problem of determining the physico-mechanical and tribological parameters of ion-plasma DLC coatings applied to a steel substrate using nitrogen to stabilize the structure and thickness of coatings. The obtained dependences of the coefficient of friction µ and the run length L of the samples up to the moment of coating destruction by the current and induction coils (λ, A) – the power of the ion flux, the amount of stabilizer nitrogen (%N) allowed not only to optimize the coating modes, but also to identify the disadvantages of DLC coatings. In particular, it was found that the coefficient of friction remains practically constant and quite small over the entire range of loads at the level of µ = 0,17. As for wear, in the range of significant loads, the experimental dependence of the friction path to destruction continuously decreases and tends to zero. Therefore, further research was aimed at developing a technology for obtaining a combined coating by alternating CrAlSiN metal-ceramic layers obtained by arc spraying by physical vacuum deposition of PVD coatings, and carbon (including diamond-like) layers obtained by laser evaporation of graphite, without extracting substrate samples from the vacuum chamber of the BRV-600 installation. As a result of combining the high wear resistance of the CrAlSiN nitride coating and the low friction coefficient of the DLC coating, the wear resistance of highly loaded tribounits is significantly increased.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>вакуумная ионно-плазменная технология</kwd><kwd>нитридные и алмазоподобные покрытия</kwd><kwd>механические и трибологические свойства покрытий</kwd><kwd>параметры нанесения покрытий</kwd><kwd>комбинированные покрытия.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vacuum ion-plasma technology</kwd><kwd>nitride and diamond-like coatings</kwd><kwd>mechanical and tribological properties of coatings</kwd><kwd>coating parameters</kwd><kwd>combined coatings.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Азаренков, Н.
