Mechanical coating formed under conditions of vibration exposure

Abstract

The study results of the zinc coating obtained on the surface of metals in the process of mechanochemical synthesis, implemented in the conditions of vibrowave systems, are presented. The features of coating formation mechanism, an activating role in its formation of free-moving, under the influence of low-frequency vibrations, indenters, are disclosed. The advantages of applying zinc coatings method in comparison with traditional methods are shown.

Optimization of transport routes based on environmental indicators

“…In most cities of the Rostov region for the period 2008-2016 there is an increase in the level of air pollution with soot, carbon monoxide, nitrogen oxides, nitrogen dioxide, phenol and formaldehyde, which is directly related to a significant increase in the fleet of vehicles in use. At the same time, there is a decrease in the level of pollution: sulfur dioxide, nitrogen oxides, hydrogen sulfide and benzopyrene, which clearly demonstrates the result of the decisions taken at the state level to restrict import of used cars and to improve quality of hydrocarbon fuels [7][8][9][10][11][12][13][14].…”

Combined process of vibratory processing and oxidation with the use of polymeric environments

“…The large number of traces covering almost the entire surface of the sample indicates the occurrence of processes of elastoplastic deformation at the micro/nanoscale and loosening of surface layer of the natural oxide film. These phenomena are of great importance in the formation of an oxide film and surface microrelief, since direct contact of the ball occurs along the oxide film [5][6][7][8].…”

“…Vibration processing provides a change in the physical and chemical properties of the surface layer of the part, as well as its activation. Given the versatility of vibration equipment, it can be used not only for coating formation processes, but also for finishing and stripping and hardening operations, which is important because reduces the cost of production [1][2][3][4][5][6][7].…”

Studying soil-reclamation state of rice agricultural landscapes

“…Plowing the green mass of colza at the rice-sowing farm on Chernoerkovskaya irrigation system in 2018 made it possible to obtain increase in the rice grain yield of 18.5 c/ha. In the case when the green mass was used for fodder (200 c/ha), E3S Web of Conferences 210, 04006 (2020) ITSE-2020 https://doi.org/10.1051/e3sconf/202021004006 and the crop residues were plowed, the increase in the rice grain yield was only 8 c/ha [23][24].…”
