Проведены экспериментальные работы, направленные на изучение трибологических характеристик MoCrN покрытий. Интерес к подобным исследованиям обусловлен в первую очередь перспективностью использования подобных покрытий в качестве антикоррозионных защитных покрытий, обладающих высокой устойчивостью к внешним механическим воздействиям, позволяющим повысить сопротивляемость стали к процессам деградации при эксплуатации и воздействию высоких температур при которых происходит ускорение процессов окисления и аморфизации. При этом подбор оптимальных составов защитных покрытий позволяет снизить износостойкость и деградацию приповерхностных слоев стальных конструкций, а также увеличить их устойчивость к механическим повреждениям в ходе трения. Определено, что изменение условий магнетронного напыления покрытий MoCrN, приводящее к изменению соотношения элементов в составе покрытий, приводит к формированию структурно – упорядоченных покрытий, что в свою очередь имеет хорошую корреляцию с результатами упрочнения и повышения сопротивляемости к износу. Согласно полученным данным, изменение соотношение компонент, и как следствие, изменение соотношения кристаллической и аморфной составляющей в составе покрытий приводит к снижению скорости износа, что свидетельствуют о повышении сопротивляемости покрытий к внешним механическим воздействиям. Результаты испытаний образцов покрытий в случае оценки устойчивости покрытий к температурному воздействию в процессе трибологических испытаний показали повышение сопротивляемости покрытий за счет вариативности изменения элементного состава и степени кристалличности.

Experimental works aimed at studying tribological characteristics of MoCrN coatings have been carried out. Interest in such studies is primarily due to the prospect of using such coatings as anticorrosive protective coatings with high resistance to external mechanical effects, allowing to increase the resistance of steel to degradation processes during operation and high temperatures at which oxidation and amorphization processes are accelerated. The selection of optimal compositions of protective coatings allows to reduce wear resistance and degradation of near-surface layers of steel structures, as well as to increase their resistance to mechanical damage during friction. It is determined that the change of conditions of magnetron sputtering of MoCrN coatings, leading to a change in the ratio of elements in the composition of coatings, leads to the formation of structurally-ordered coatings, which in turn has a good correlation with the results of hardening and increasing resistance to wear. According to the obtained data, the change in the ratio of components, and as a consequence, the change in the ratio of crystalline and amorphous components in the composition of coatings leads to a decrease in the rate of wear, which indicates an increase in the resistance of coatings to external mechanical influences. The test results of coating samples in the case of assessing the resistance of coatings to temperature effects in the process of tribological tests showed an increase in the resistance of coatings due to the variability of changes in the elemental composition and degree of crystallinity.
