“…In the SEM images of Figure 4, smooth scratches are observed for AlCrN and some black areas, which could correspond to oxides as it was stated in the literature. 27 Different chemical reactions may occur due to the high local pressure on the contact surface during sliding, since Hertzian stresses are about 2 GPa, and flash temperature. They can alter the chemical and phase composition of the outer surface layer, as well as its mechanical properties.…”

TiAlN and AlCrN coatings are widely used in applications that require high stress resistance. In this work, the tribological behaviour of physical vapour deposition (PVD) TiAlN and AlCrN commercial coatings deposited on AISI martensitic stainless steel is studied. Microstructure of the coatings was analysed by X-ray diffraction (XRD), optical microscopy (OM) and scanning electron microscopy (SEM) and nanohardness was measured. Pin-on-disk and abrasive wear tests were performed. Adhesion was evaluated using Rockwell C Indentation and scratch test. The thickness of both coatings was approximately 3 µm. AlCrN lost 30 and 10 times less volume than TiAlN in pin-on-disk tests, under low and high loads, respectively. The steady friction coefficient value was also lower. This indicated that the AlCrN coating had a better performance under sliding conditions. On the other hand, the mass loss was similar for both coatings under abrasive wear, even under severe conditions. In the scratch tests, TiAlN coating failed at 60 N load and AlCrN coating at 70 N, the latter showing a higher value of critical load. The deformation was similar for both coatings as it could be observed in the profiles obtained by a mechanical profilometer at 60 N, however, AlCrN did not show film delamination. This enhanced performance can be attributed to higher fracture toughness and load carrying capacity, which not only improved the mechanical properties of the coating but also its adhesion to the stainless-steel substrate.

In aerospace, aviation, nuclear power, and other high-tech fields, some essential moving parts must operate under high vacuum, high load, intense radiation, and other conditions. Under such extreme conditions, only solid lubricating materials can meet the lubrication requirements. Traditional material modification methods have problems such as high energy consumption, severe pollution, and narrow scope of application. Plasma modification technology can overcome these shortcomings. This paper focuses on several commonly used plasma preparation techniques for solid lubricating coatings, including plasma chemical heat treatment, physical vapor deposition, plasma immersion ion implantation and deposition, plasma spraying, and plasma electrolytic oxidation. Subsequently, the material systems of metal-based solid lubrication coatings are reviewed: soft metals, oxides, sulfides, nitrides, and carbon-based materials. Finally, found that the development of new solid lubricants, the improvement of existing preparation technology, and the development of new processes are the key development directions in the future.

The subject of research in this article is the processes of excitation of a vacuum-arc discharge in plasma sources by unconventional methods: the transition of a glow discharge into an arc discharge (TGA) and arc initiation using laser radiation (LR). The goals are to increase the service life of ignition systems (IS) for plasma sources to expand their technological capabilities and the quality of the resulting coatings. The tasks: to investigate the modes in which non-traditional IS stably excite an arc discharge and ensure their high service life. The methods used are analytical and experimental research methods, which were carried out using the developed new devices. The following results have been obtained. The study of arc excitation using a TGA in a system of Penning-type electrodes showed that the use of a plasma source with such an IS is advisable in processes in which reaction gases are used to form compounds with its material on the cathode surface. Otherwise, after several hundred triggering, the probability of PTD decreases to values of 10...50 %, which is explained by the cleaning of the cathode surface from various inhomogeneities. The ignition of the TGA arc using dielectric stimulators of the cathode spot (CS) expands the technological capabilities of the plasma source. Here, the arc discharge stably ignites in the pressure range from 10-2 to 10 Pa, with voltage pulses of the order of 2 kV in a magnetic field with a strength of 5.6 104 A/m and a starting pulse energy of 2 J. The design of a plasma source with a combined IS has been developed, which makes it possible to achieve the maximum reliability of the excitation of a vacuum arc. A plasma source with a combined IS has a reliability of starting the device in the pressure range of 10-2 ... 5 Pa, the presence of a magnetic field of 104 ... 105 A/m and amplitude of starting pulses of 1.5...2.0 kV close to 100%. The conditions under which the formation of vapor condensate of the plasma source cathode material on the surface of the LR input window does not occur are considered, and it is proposed to solve this problem by supplying energy to the condensation zone directly to the formed condensate layer. Conclusions. The use of non-traditional methods of excitation of a vacuum-arc discharge was substantiated and studied: using TGA and LR, a combined IS was developed, in which traditional and non-traditional methods of arc ignition are combined using the advantages of each method, parameters were found under which the IS work under study reliably and have high resource.
