Трибологические характеристики покрытий изучались по схеме «шар-диск» до и после нанесения покрытия Cr2N. В качестве контртела применялся шарик из стали ШХ15 (без покрытия). Анализ поперечных сечений дорожек износа после испытаний свидетельствует о том, что после нанесения покрытий износ фактически отсутствует. Образец с покрытием обладает коэффициентом трения 0,14–0,17, т.е. не превышает значение коэффициента трения (&lt;0,2) предъявляемое к материалам в сухих парах трения. Методом потенциометрии была определена коррозионная стойкость стали ШХ15 до и после нанесения тонкопленочного покрытия Cr2N. Коррозионные испытания проводили на потенциостате-гальваностате Р150, в 4% растворе азотной кислоты (HNO3). Результаты испытания показали, что после нанесения покрытия Cr2N скорость коррозии составила 0,191 см/год, т.е. в два раза меньше по сравнению со сталью ШХ15 без покрытия.</p></abstract><trans-abstract xml:lang="en"><p>To determine the effect of Cr2N coating on the performance of rolling bearings, this article has studied the tribological and corrosion characteristics of thin-film coatings obtained by the MF method. The tribological characteristics of coatings were studied using the “ball on disk” scheme before and after Cr2N coatings were applied. As the counterbody was used a ball of SchCh15 (without coating). Analysis of cross-sections of wear tracks after testing indicates that there is virtually no wear after coating. The coated sample has a coefficient of friction of 0.14 0.17, i.e. it does not exceed the value of the coefficient of friction (&lt;0.2) required for materials in dry friction pairs. The method of potentiometry was used to determine the corrosion of steel SchCh15 before and after applying a thin-film coating Cr2N.Corrosion tests were performed on a potentiostat-galvanostat P150, in a 4% solution of nitric acid (HNO3). The test results showed that after applying the Cr2N coating, the corrosion rate was 0.191 cm/year, i.e. half as much as that of uncoated steel SchCh15.</p></trans-abstract><funding-group xml:lang="ru"><funding-statement>В статье использованы результаты, полученные при поддержке программы целевого финансирования МОН РК, грант BR052236748.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Котов С.Ю., Беляев Г.Я.
