“…One can see that for both technologies, the base parameter defining precipitation or absence of the Cr 2 N phase is rather an energy factor (defined by the applied bias potential [58,59]) and working medium than the partial pressure of reaction gas [55][56][57]. Moreover, as it will be shown further during analysis of the results, the Cr 2 N phase can contribute to improving the mechanical properties of the coatings [31,39].…”

featUres of investigations of MUltilayer nitride coatings based on cr and zr The studies of the structure and properties of nanoscale multilayer coatings of Zrand Cr-based refractory metals obtained by the vacuum arc cathode deposition are summarized in a brief review of the literature data. A comparative analysis of the microstructure and properties of ZrN/CrN composite coatings depending on the deposition conditions (constant negative potential of the substrate, pulsed highvoltage bias potential, partial pressure, reaction gas velocity) and modulation period for multilayered structure is carried out. General regularities consisting in the presence of the columnar structure and the growth texture are revealed. They show that there is a prevailing (111) orientation for investigated coatings. Conditions for obtaining improved physical, mechanical, and tribological properties of the coatings are determined.

“…До переваг використання латуні у процесах DLE належать легкість лазерного та механічного оброблення, низький коефіцієнт тертя. Низьку зносостійкість в умовах сухого тертя ковзання, характерну для латуні, а також вплив агресивних середовищ під час друкування підвищують нанесенням на гравійовану поверхню захисного зносостійкого покриття нітриду хрому CrN [4,5]. Тенденцією сьогодення є те, що подальше захисне хромування здійсню-ється не електрохемічним способом, як на час розроблення методу [1, 2], а нанесенням захисного нітрид-хромового покриття вакуумним напорошенням (PVD) під час розпорошення хромової мішені в атмосфері азоту [6].…”

Проведено дослідження йонного оброблення поверхні катаної латуні Л63 в потоці плазми геліконного розряду в аргоні. Встановлено, що йони арґону з високою густиною, генеровані геліконним розрядом, не тільки інтенсивно розпорошують поверхню латуні, очищають її від неконтрольованих домішок, значно підвищують клас чистоти поверхні латуні, але й

“…Coatings based on chromium nitride are of interest, both for basic research and for applied use, taking into account the high functional properties in nitride chromium. Thus, CrN coatings is one of the widely used as protective in such areas as automotive, aerospace industry [7], for die and mould, mechanical components, and artificial joints to increase their service life due to their excellent oxidation resistance, corrosion resistance, low friction coefficient, and high wear resistance [8][9][10][11][12].…”

To reveal the regularities of structural engineering of vacuum-arc coatings based on chromium and its nitrides, the influence of the main physicotechnological factors (the pressure of the nitrogen atmosphere and the bias potential) in the formation of coatings was studied. It was discovered that during the deposition of chromium coatings the formation of the texture axis [100], as well as the macrodeformation of compression is happening. The supply of a high-voltage negative pulse potential to the substrate increases the mobility of the deposited atoms and leads to relaxation of the compression deformation. As the pressure increases from 210-5 Torr to 4.810-3 Torr, the phase composition of the coatings changes: Cr (JCPDS 06-0694) → Cr2N(JCPDS 35-0803) → CrN(JCPDS 11-0065). The supply of high-voltage pulses leads to the formation of a texture of crystallites with parallel growth surfaces planes having d ≈ 0.14 nm. The structure obtained by pulsed high-voltage action makes it possible to increase the hardness of the coating to 32 GPa and reduce the friction coefficient to 0.32 in the "chromium nitride-steel" system and to 0.11 in the "chromium nitride-diamond" system. The results obtained are explained from the viewpoint of increasing the mobility of atoms and the formation of cascades of displacements when using an additional high-voltage potential in the pulse form during the deposition of chromium-based coatings.
