Abstract

Interest in thin-film protective coatings based on nitride compounds of molybdenum and chromium is due to the great prospects for their use as wear-resistant anti-corrosion coatings with high resistance to both external effects in the form of mechanical friction, pressure, and corrosion processes, when exposed to aggressive media, hydrogenation or high temperatures. However, the stability of nitride coatings are primarily determined by the conditions of their obtaining, which not least depend on the power of magnetron sputtering, the variation of which allows you to change the ratio of elements in the composition of coatings. The key objective of this research is to measure the strength characteristics measured by indentation method depending on the conditions of obtaining coatings under variation of sputtering power, as well as to establish the influence of variation of conditions of obtaining thin film coatings on the change of hardness and hardening factors. According to the presented data, changing the conditions of magnetron sputtering by varying the power leads to the formation of stronger stable coatings with high resistance to cracking under changing external load. In the course of research it was determined that changing the conditions of magnetron sputtering coatings, leading to an increase in the concentration of molybdenum in the composition of coatings leads to more than 60–80% hardening, as well as an increase in resistance to cracking under external influences.
