Wear Resistance Increase of Samples Tribomating in Oil Composite with Geo Modifier КGМF-1

Determining the rational composition of tribologically active additive to oil to improve characteristics of tribosystems

“…We used the four-ball friction machine, in which the oil media of mated were tested in a pyramid of four balls, three lower balls of which were fixed motionless in the cup, where the tested oil was poured, and the top ball rotated in a vertical spindle. The four-ball friction machine was used to study the lubricating capacity of composite lubricants [2]. Average values of critical load, welding load, wear indicator, characterized by the diameter of a spot from wear from the applied critical load for the corresponding lubricating media were determined in the course of research.…”

“…Responses or resulting features during the experiment were: Y1 -magnitude of wear (mm) → min; Y2 -critical load (N) →max; Y3 -welding load (N) →max. Table 1 Formation of factors and their levels for the experiment The preliminary choice of factors' levels was made based on the formalization of a priori information of the series of experiments [1,2,6,23]. The values of the lower factor were determined according to their impact on the corresponding response function or the possibility of manifestation of the negative processes in the junction during of the friction process.…”

“…In this case, metal-organic materials of surfaces of mated parts, which are operated under conditions of contact with overheated, abrasive substances, are used. However, having high electrical and thermal conductivity, working surfaces of the parts have low wear resistance [2]. In turn, high electrical conductivity of the materials of parts leads to rapid tribo-electrization of surface layers, which create an internal electric field that can affect the particles of additives and particles of wear.…”

Analysis of tribological efficiency of movable junctions "polymeric­composite materials ‒ steel"

“…In this study, the authors did not investigate the impact of these additives in the presence of abrasive particles. Using wear-resistant and inactive surface layers of materials for tribojunction of parts makes it possible to extend the service life of both separate components and a working environment [6]. However, the authors did not consider the characteristic of relative abrasive resistance of the examined elements of tribojunctions.…”

Studying the tribological properties of mated materials C61900 - A48-25BC1.25BNo. 25 in composite oils containing geomodifiers

“…It follows from the results of the research into the properties of Mg 6 Si 4 O 10 (OH) 8 geomodifiers [15]. It was determined that friction geomodifiers are based on a large group of minerals [16] that have similar chemical composition, where magnesium can be replaced with iron and nickel [17]. Serpentine rock includes several types of serpentine, magnetite and chromic inclusions, and the variation of chemical elements used as a mixture of geomodification compositions [18].…”
