Interrrelations between the chemical composition and the main physicochemical and operational properties of the cutting fluid, which determine its efficiency in increasing the processing productivity and surface quality in the course of grinding have been investigated. 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.

The tube bundle for simulating a steam generator leak during the outflow of the light phase is two rows of 22 × 3.5 pipes welded to a plate with a pitch of 33 mm. The data were obtained for tube bundles with two different types of holes for the outflow of the vapor phase: a slit hole of 13 × 1 mm and a round hole with a diameter of 4 mm. The processing and analysis of the results allowed us to conclude that when a steam-water mixture enters the heavy liquid metal coolant circuit, the oxide coatings become thinner depending on the location of the tube in the bundle and the shape of the discharge hole. There is a noticeable decrease in microhardness (by 49 HV for a tube bundle with a round discharge hole and by 23 HV for a tube bundle with a rectangular discharge hole), which is more pronounced when approaching the discharge hole and depends on the orientation of the tube surface onto which the mixture enters, relative to the leak. The data are recommended for use in assessing the consequences of a large leak in a horizontal steam generator in installations with heavy liquid metal coolant.","PeriodicalId":633,"journal":{"name":"Journal of Friction and Wear","volume":"45 6","pages":"370 - 374"},"PeriodicalIF":0.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612182","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}

The friction surfaces were examined by confocal laser microscopy and scanning electron microscopy. The elemental composition of the friction surfaces was determined with the help of energy-dispersive X-ray spectroscopy (EDX) and X-ray photoelectron spectroscopy (XPS). The contribution of the chemical component (formation of iron oxides) to the anti-wear process was analyzed. 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 established that a high level of fatigue strength of the aluminum alloy and the absence of adhesion with respect to a bismuth-alloyed steel surface provide conditions leading to the manifestation of the wearless effect (zero wear) at friction velocities amounting up to 9 m/s and at normal loads amounting up to 250 N.

It is established that an increase in the cutting ability of a diamond cutting wheel with an increase in the concentration of diamond grits in the diamond-bearing composite material of the segments is associated not only with an increase in the number of diamond grits on the segment surface, but also with a change in the mechanism of contact interaction of the diamond-bearing composition with the workpiece. It is established that an increase in grit size, even with a small change in concentration (from 17.5 to 25 rel. %) in the segment, changes the cutting ability of the tool. Diamond grits reduce the contribution of frictional interaction of the bond with the workpiece, and their higher concentration in the segment leads to a decrease in impact loads on the grit. When cutting a steel pipe, an increase in the concentration of diamond grits reduces the frictional component of the contact interaction of the diamond-bearing composite material with steel, reducing the thermal effect of frictional interaction, and an increase in their size helps to increase the strength of their fixation by the bond, leveling the influence of the thermal effect of frictional interaction of the bond with steel and the increase in its temperature in the frictional contact zone.","PeriodicalId":633,"journal":{"name":"Journal of Friction and Wear","volume":"45 6","pages":"375 - 381"},"PeriodicalIF":0.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612179","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}

It is shown that with a decrease in the thickness of the coating, a significant increase in the level of shear stresses acting in the base during friction is recorded. The patterns of wear under dry friction conditions of AISI 304 and AISI 420 high-chromium steels modified with nitrogen ions, differing in the hardness of the base and the thickness of the nitrided layer, have been studied. It is concluded that the abnormally high wear rate of a thin nitrided layer in AISI 304 steel is associated with the accumulation of shear strains in the plastic austenitic base during friction, as well as with a high gradient of hardness values along the depth of the hardened layer in the steel and a γ → α phase transformation in the base during frictional interaction. The influence of base hardness on the wear resistance of AISI 420 nitrided steel was studied. It has been established that an increase in the hardness of the AISI 420 steel base leads to a decrease in the wear rate of thin nitrided layers at the later stages of tribological tests, which is associated with a slowdown in the accumulation of shear strains in the solid steel base during friction.","PeriodicalId":633,"journal":{"name":"Journal of Friction and Wear","volume":"45 6","pages":"322 - 331"},"PeriodicalIF":0.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143612193","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}

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}
