Thickness of vibrational mechanochemical solid-lubricant coating in friction pairs of transport engineering products

Abstract

The paper studies the thickness of the vibrational mechanochemical solid-lubricant coating of molybdenum disulfide which is widely used in transport and technological systems.

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

“…In previously published works [8][9][10][11][12][13] there is information about the formation of the surface layer in the process of vibration processing in the environment of metallic working media. These processes are accompanied by plastic deformation of the surface layers of the metal under conditions of multiple dynamic contact of particles of the working medium with the part.…”

“…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].…”

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].…”

Studying soil-reclamation state of rice agricultural landscapes

“…This problem can be solved by phytomelioration and replacing soybeans in the second field with colza (Table 3). [25] When cultivated for grain or as green manure, winter colza acts as phytomeliorant. It develops powerful, deeply penetrating into the soil (up to 3 m) tap root system, which piercing the soil improves its water and air permeability.…”
