Микроструктура синтезированных покрытий, рельеф лицевой поверхности аттестованы сканирующим электронным микроскопом. Анализ соответствия покрытия а-С осуществлялся методом нарушенного полного внутреннего отражения (НПВО) при использовании ИК Фурье-спектрометра. Твёрдость и приведённый модуль упругости были получены методом непрерывного индентирования пирамидой Берковича. Интенсивность износа и коэффициент трения определены в режиме трение скольжения. Результаты комплексного экспериментального исследования покрытий являлись основой для построения конечно-элементной модели индентирования двухслойной упругопластической среды с различным сочетанием упругих и пластических характеристик, и относительных толщин слоёв. Экспериментально установлена корреляция параметров рассматриваемых покрытий H/E и H3/E2 и интенсивности износа. Теоретически установлены функциональные зависимости твёрдости и приведённого модуля упругости в зависимости от относительной толщины лицевого метастабильного слоя а-С. Определено оптимальное соотношение толщин составляющих слоёв TiN/a-C покрытия при заданных упругопластических характеристиках материалов, которое будет обладать наилучшими триботехническими характеристиками.</p></abstract><trans-abstract xml:lang="en"><p>This work investigates the mechanical properties and tribological characteristics of TiN (single layer) and TiN/a-C (double layer, two types of combinations of elastic-plastic properties of media) coatings based on experimental and theoretical approaches. The microstructure of the synthesized coatings and the relief of the front surface were examined using a scanning electron microscope. The analysis of the conformity of the a-C coating was performed using the disturbed total internal reflection method with an IR Fourier spectrometer. The hardness and reduced elastic modulus of the samples were determined through continuous indentation using a Berkovich pyramid. The intensity of wear and the friction coefficient were determined in a sliding friction mode. The findings of a thorough experimental investigation into the coatings were instrumental in formulating a finite element model of indentation into a two-layer elastic-plastic medium, incorporating varied combinations of elastic and plastic characteristics, as well as distinct relative layer thicknesses. The correlation between the parameters of the considered coatings H/E and H3/E2 and the wear intensity was established through experimental means. Theoretically, the functional dependencies of hardness and reduced elastic modulus on the relative thickness of the face metastable layer a-C were established. The optimal thickness ratio of the TiN/a-C coating layers has been determined for given elastic-plastic characteristics of the materials. Such a coating will exhibit optimal tribological characteristics.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>многослойные покрытия TiN/a-C</kwd><kwd>индентирование упругопластических сред</kwd><kwd>механические свойства TiN</kwd><kwd>a-C</kwd><kwd>триботехнические характеристики a-C</kwd></kwd-group><kwd-group xml:lang="en"><kwd>multilayer TiN/a-C coatings</kwd><kwd>indentation of elastic-plastic media</kwd><kwd>mechanical properties TiN</kwd><kwd>a-C</kwd><kwd>tribological characteristics a-C</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">Aghaei A.A., Eshaghi A., and Karami E.
