Abstract The effect of argon ion irradiation with an energy of 40 keV in the dose range of 1016 - 1018 ion/cm2 on the formation of the surface layers composition, changes in the morphology and mechanical properties (microhardness, and wear resistance) of carbon steel AISI 1020 with a deposited ion-plasma coating Ni80Cr20 was studied. It is shown that irradiation with doses greater than 1017 ion/cm2 leads to the formation of a layer consisting of nickel, chromium and iron. The most optimal treatment mode for improving wear resistance is irradiation with a dose of 5.1017 ion/cm2.

The development of aerospace engineering and mechanical engineering directly depends on the development of new metal materials and advanced technologies. The problem of creating materials and their types of processing to increase the level of operational properties is relevant in connection with the complication and tightening of working conditions of modern technologies. One of the most important tasks of contemporary aircraft construction is to increase the operational properties of the surface layer. The purpose of the article is to elucidate the effect of high-current electron beams of microsecond duration on changes in the surface layers of the heat-resistant multicomponent ion-plasma coating Ni-Cr-Al-Y under various conditions. Using a complex of metallophysical research methods, the physicochemical and structural-phase states of the surface layer were studied before and after modification of the samples. These samples were coated with heat-resistant condensed ion-plasma coatings of three different compositions using nine high-current electron beams in 9 modes with different values of electron energy and number of pulses in the selected interval of electron energy. An analysis of the structural phase changes occurring during modification was carried out. Cylindrical samples of targets made of heat-resistant nickel alloy ZhS36 coated with ion-plasma condensed multicomponent coating SDP-2 + VSDP-16. These samples were used according to serial technology, both with subsequent modification using highcurrent electron beams and without modification. It was found that chromium in the initial state is unevenly distributed: chromium is present in the particles; the matrix is depleted in chromium. The research results can be useful for scientists to study the properties of heat-resistant multicomponent ion-plasma coatings Ni-Cr-Al-Y and the effect of high-current electron beams on it, as well as for the manufacture of more heat-resistant materials in aerospace engineering and mechanical engineering.

Comparative studies of the effect of discrete surface hardening by standard ion-plasma technology and discrete oxidation technology on wear resistance have been carried out. Metallographic studies have shown that discrete oxidation has a polycrystalline structure. It was found that the technology of discrete oxidation makes it possible to increase the hardness by 31% in relation to the uncoated material, and the wear resistance of the cutting tool with oxidation is 1.5-3 times higher than that of the tool hardened by the standard ion-plasma technology.

Tribological investigations had been carried out on the plasma coating (Al2O3+ ZrO2) below dry and moist abrasion stipulations according to ASTM G134. Commercial motor oil 20W40 was used as a lubricant. At a rotational speed of 200 rpm, all experiments were carried out with ordinary loads of 10, 15 and 20 Nm. Electron microscopy for scanning and AFM was used to study of the layer sprayed with paint. The outcomes of the SEM and AFM evaluation confirmed that abrasive wear is normally decided by abrasive wear in dry abrasive conditions. The lubrication and moisture check confirmed a major reduce in wear from 10 to 15 N below regular loading, and a corrosion fee larger than 15 N was once discovered below regular loading. No impact of lubrication on wear used to discovered at high loading. No impact of lubrication on wear used to be discovered at high loads. It was also cited that the plasma coating manner to improve wear resistance. The experimental statistics acquired in this study are tremendous engineering functions such as reducing equipment and internal combustion engines.

Formed Structure

Deposition of a titanium or a copper film onto the surface of commercially pure A7 aluminum and irradiation of the “film/substrate” system with an intense pulsed electron beam are carried out in a single vacuum cycle. Formation of a surface doped layer with a thickness of (20-30) μm is revealed. It is shown that the modified layer has a multiphase structure of a cellular rapid solidification of the submicron-nanosized range. Irradiation parameters are determined. It is established that the developed modification method allows forming a surface doped layer with the microhardness more than 4 times (Ti-Al alloy) or more than 3 times (Cu-Al alloy) greater than the microhardness of A7 aluminum; the wear resistance of the surface alloy Ti-Al exceeds the wear resistance of the initial aluminum in ≈2.4 times; doping of aluminum with copper is accompanied with an increase in the wear resistance of the material in ≈1.5 times.
