The studies have been performed in order to reveal the character of physicochemical phenomena in a contact zone between abrasive grains and metal under processing with the use of an RSZ-2 unit. A mechanism determining the effect of thermoelectric phenomena on the interaction between the abrasive grain and the metal in the presence of a lubricating-and-cooling agent (cutting fluid) in the course of grinding has been revealed.

It was found that despite the difference in the spatial structure of the used CNSs, the processes occurring in the friction zone are chemically similar. It has been demonstrated that with the use of both model lubricants, protective oxide films consisting of iron oxides (FeO, Fe2O3, Fe3O4) are formed in the contact zone. The chemical composition of the oxide film and the quantitative ratio of the formed iron oxides are not significantly affected by the type of CNS additives used.

It is shown that the creation of a microporous layer contributes to an increase in the tribotechnical characteristics of surfaces under lubrication conditions. It is shown that the use of the electrolyte-plasma surface treatment method allows high-performance formation of a microporous surface layer that does not require further mechanical processing, and in one technological cycle is able to polish it. It is shown that the use of preliminary preparation of the surface layer for nitriding using high-energy processing methods can significantly increase the wear resistance of the microporous layer. The results of comparative tests of microporous surfaces with various processing options are presented. It is shown that the use of microporous surfaces in conditions of friction with lubrication makes it possible to increase the wear resistance of 40X and 40KHN steels by about 1.5–2 times, and their nitriding provides an increase in wear resistance compared with simple traditional nitriding by about three times, and compared with microporous surfaces without nitriding by more than nine times.","PeriodicalId":633,"journal":{"name":"Journal of Friction and Wear","volume":"45 6","pages":"332 - 336"},"PeriodicalIF":0.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612222","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Changes in the microstructural characteristics during metal tribodeformation are analyzed from the standpoint of the Rehbinder effect, which determines the possibility of selective transfer (wear-free mode) in tribological conjunction. It is shown that during friction of bronze in lubricating-dispersion media characterized by relatively low surface activity, the effect of the medium on the surface structure of the tribomaterial is based on the implementation of the surface-hardening effect, the total density of dislocations in the deformed near-surface layer increases. The wear intensity in this case is Ih ≈ 1.5 × 10–7 to 4.0 × 10–8. When bronze is subjected to friction in moderately surface-active media, both surface-plasticizing and surface-hardening effects are realized, with the latter predominating. In this case, the wear intensity decreases slightly, taking values in the range of Ih ≈ 1.2 × 10–7 to 1.5 × 10–8. During tribotesting of bronze in media with increased surface activity, the wear intensity of bronze remains at a fairly low level: Ih ≈ 2.2 × 10–8 to 3.0 × 10–8. However, in this case, two crystallographically isostructural solid solutions are formed in the near-surface layer of the tribomaterial, one of which is enriched with copper.

In the course of a numerical experiment on this model, it is found that the case of adhesive contact between the layers of the road pavement corresponds to the presence of one clearly expressed frequency extremum on the acceleration AFC. The case of “complete slippage” corresponds to the presence of a number of frequency extrema on the acceleration AFC. In this case, when modeling the full slip at the boundary of the half-space lower layer and the underlying half-space and varying the elastic modulus of the half-space, the presence of a clearly defined frequency extremum in the range of 426–531 Hz is noted, presumably corresponding to oscillations of the underlying half-space itself.
