“…Thus, regardless of the substrate, an improvement in erosion resistance was obtained. Subsequent studies confirmed the improvement in erosion resistance (a decrease in cumulative weight loss/volume loss or erosion rate) due to deposition of hard PVD coatings [110,111,114].…”

“…These changes were related with hardness and thermal conductivity of the balls. Comparison of the wear rate of the 4-µm-thick TiAlN monolayer coating and the 4-µm-thick Ti-Al-Mo-N multilayer coating with alternating layers of Ti and Mo enriched nitride showed higher wear resistance (lower wear rate) of the multilayer coating [114]. Also investigations of CoF and life of tools with 5 µm-thick TiN/TiC, TiN and TiC coatings showed a lower friction coefficient and about twice the life of tools with the multilayer coating compared to the monolayers [138].…”

“…Investigations of CrN/CrCN coatings showed that the thinner the bilayer, the better the wear resistance [140]. Comparable results of an effect of bilayer thickness were obtained in testing TiN/Ti, Ti-Al-Mo-N and TiN/CrN multilayer coatings with nanometric layer thickness [114,143]. The wear decreased with decreasing bilayer thickness.…”

“…The study on the influence of the layer thickness of the multilayer coating on the wear resistance showed that the wear rate decreases with the decrease of the layer thickness [114,143]. For example, TiN/Ti coating with a total thickness of 1.2 µm and a layer thickness of 20 nm had about 50% less wear than TiN/Ti coating with the same total thickness and a layer thickness of 100 nm.…”

Due to the increasing maintenance costs of hydraulic machines related to the damages caused by cavitation erosion and/or erosion of solid particles, as well as in tribological connections, surface protection of these components is very important. Up to now, numerous investigations of resistance of coatings, mainly nitride coatings, such as CrN, TiN, TiCN, (Ti,Cr)N coatings and multilayer TiN/Ti, ZrN/CrN and TN/(Ti,Al)N coatings, produced by physical vapor deposition (PVD) method using different techniques of deposition, such as magnetron sputtering, arc evaporation or ion plating, to cavitation erosion, solid particle erosion and wear have been made. The results of these investigations, degradation processes and main test devices used are presented in this paper. An effect of deposition of mono- and multi-layer PVD coatings on duration of incubation period, cumulative weight loss and erosion rate, as well as on wear rate and coefficient of friction in tribological tests is discussed. It is shown that PVD coating does not always provide extended incubation time and/or improved resistance to mentioned types of damage. The influence of structure, hardness, residence to plastic deformation and stresses in the coatings on erosion and wear resistance is discussed. In the case of cavitation erosion and solid particle erosion, a limit value of the ratio of hardness (H) to Young’s modulus (E) exists at which the best resistance is gained. In the case of tribological tests, the higher the H/E ratio and the lower the coefficient of friction, the lower the wear rate, but there are also many exceptions.

“…Мультислойные arc-PVD покрытия Ti-Al-Mo-N, характеризующиеся чередованием слоев на основе сложного нитрида (Ti, Al)N [1] и нитрида молибдена, демонстрируют высокую износостойкость [2][3][4]. С одной стороны, она определяется значением твердости до 40 ГПа, с другой -низким коэффициентом трения за счет явления адаптации покрытий к интенсивному трению путем образования в зоне трения оксида MoO 3 , играющего роль твердой смазки [5,6].…”

Проведены сравнительные исследования структурных характеристик и функциональных свойств покрытий Ti-Al-Mo-N и Ti-Al-Mo-Ni-N, полученных методом ионно-плазменного вакуумно-дугового осаждения, с целью изучения влияния наноструктурирующей добавки никеля. Покрытия характеризовались слоистой архитектурой с чередованием слоев нитридов титана и молибдена. Концентрация молибдена составляла порядка 22 ат.%, никеля -7 ат.%, что отвечает оптимальным количествам для наилучших прочностных и трибологических свойств. Показано, что при введении никеля происходит снижение периода модуляции покрытия с 60 до 30 нм с одновременным повышением твердости с 37 до 45 ГПа. При этом увеличивается вязкость разрушения покрытий, о которой судили по относительной работе пластического деформирования и параметрам H/E, H 3 /E 2 . Добавка пластичного никеля в структуру твердого нитридного покрытия способствовала уменьшению уровня сжимающих макронапряжений в материале от -2,25 до -0,58 ГПа, что, однако, не приводило к снижению твердости и трещиностойкости, как было показано в ходе испытаний по измерительному царапанию. Сделан вывод о том, что фактором, определяющим физико-механические характеристики покрытия, является не макронапряженное состояние, а измельчение зеренной структуры материала покрытия. Введение никеля положительно сказывается на жаростойкости покрытия, которое успешно защищает материал подложки от окисления при температурах до 700 °C, что может быть обусловлено вероятностью образования Ni-содержащих оксидов NiMoO 4 и NiTiO 3 на поверхности. При этом их появление, разрушение и действие в качестве абразивных частиц могут быть причиной изменения механизма изнашивания при трении в условиях высоких температур.
