For all studied samples, relaxation parameters were found to depend on the sample type and exhibit a consistent increase with increasing of indenter load. A detailed study of the relaxation parameters (he, he-p, and hres) allowed the authors to determine the mechanisms of plastic deformation of different quartz types during nanoindentation. Computer visualization of the surface topography around the indentations confirmed the involvement of the rotational-translational deformation mechanism of different types of SiO2 crystals in the formation of hardness indentations. It is shown that the rotational mechanism makes a greater contribution to quartz indentation in the low-load range (P = 10–50 mN), while the contribution of the translational mechanism increases with load increasing (P = 100–500 mN) and during the transition in the series α-SiO2 → p-SiO2 → a-SiO2.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 3-6","pages":"215 - 223"},"PeriodicalIF":0.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is shown that at current frequencies up to 5 kHz, the eddy fields cover almost the entire volume of the melt. Increasing the frequency to 25 kHz and above leads to their concentration in the near-surface and near-wall zones. It is established that an increase in the current frequency results is a monotonic rise in the electric field strength. The magnetic field strength increases abruptly, reaching about 90% of its peak value, and then the maximum at a frequency of 100 kHz. Further, the curve enters the saturation mode. It is shown that despite a significantly uneven distribution of electromagnetic fields at high frequencies, a relatively high uniformity index is ensured, ranging from 1 at 5 kHz to 0.45 at 200 kHz. At the same time, a stable integral force effect is exerted on the entire volume of the melt, while the peak electromagnetic force density increases by more than two times with increasing current frequency. The data obtained in the work show that the proposed method of joint processing provides wide-range regulation of the characteristics of the energy impact on the melt, which, ultimately, will make it possible to find conditions for obtaining a favorable structure and improved properties of cast metal that are rational in terms of the price-quality ratio. This should ensure its adaptability to modern technological processes for obtaining castings and its innovative appeal.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 3-6","pages":"196 - 201"},"PeriodicalIF":0.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The formation of a gradient of structural and phase changes is demonstrated, which is determined by changes in temperature and diffusion intensity, as well as the cooling rate during quenching. The tribological effectiveness of local treatment is revealed, caused by the oxide layers acting as a lubricant in combination with a high-hardness matrix and increased load-bearing capacity of the surface profile after treatment. The presented treatment method reduces mass and volume wear by up to 32 times in the contact zone of the electrolyte jet with the surface. The polarization resistance in the sodium chloride medium after local treatment of the steel surface is found to increase, which is due to the influence of nitride and oxide phases.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 3-6","pages":"179 - 188"},"PeriodicalIF":0.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scanning electron microscopy and energy-dispersive X-ray spectroscopy methods were used to study the morphology and elemental composition of chromium oxide coatings formed on AISI 304 stainless steel. The electrochemical impedance spectroscopy (EIS) method was used to study the electrochemical properties of the coating as well as to assess its subsurface structure. It was found that adding silicon oxide to the electrolyte enables the formation of a crack-free coating, while variations in its concentration influence the crystallite size of the deposited structure. An increase in the concentration of silicon oxides in the electrolyte results in a higher silicon content in the coating. The EIS results show that the increasing resistance of the coatings formed in modified electrolytes indicates an improvement of their protective properties. An analysis of equivalent circuits allows to make conclusions on the layered structure of the obtained coatings.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 3-6","pages":"247 - 256"},"PeriodicalIF":0.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The DSC results revealed a two-stage thermal behavior in all samples: an initial increase in heat flow up to ~300°C attributed to the desorption of surface-bound impurities, followed by a nearly linear trend at higher temperatures, indicating thermal stability. Both DTA and DTG analyses showed additional features above 650°C, particularly, in Nd0.5Ca0.5MnO3, where signs of oxidative transformations and mass variations were observed. Those effects were found to be irreversible, as confirmed by the absence of corresponding features during cooling. Furthermore, the specific heat capacity measurements demonstrated nearly identical thermal behavior across all samples at lower temperatures, with material-specific divergence becoming evident above 300°C.

Using lamellar samples of structural steels as an example, it has been demonstrated that, in the case of organic film removal (approximately 100 μm thick) employing an experimental system with continuous wave laser, it is relatively easy to achieve simultaneous removal of the original organic coating and the formation of a significantly hardened surface layer on steel with a thickness of at least 80 μm. This effect is observed for medium-carbon steel (such as grade 65Г steel), but not for low-carbon steels. According to the obtained data, the surface hardening factor, defined as the increase in microhardness of the metal surface layer (relative to the bulk steel) after laser cleaning, falls within the range ks = 1.9–2.9. The highest level of the base surface hardening ks ≈ 2.9) is achieved at a laser heating power of at least 300 W in the scanned spot (with a side effect of partial surface melting after removal of organic film). In this mode, the specific energy consumption is about 920 J/(cm2 of film) for an estimated dimensionless heating process parameter KP varying within the range of 350–500. As it has been revealed, a lower surface hardening factor can be obtained at heating powers not exceeding 200 W, but with increased energy consumption and without the side effect of melting the steel base. The results obtained regarding the ability to vary the physical and mechanical properties of the cleaned steel surface create prerequisites for further industrial application of this combined method for cleaning and surface hardening of various parts.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"62 3-6","pages":"287 - 295"},"PeriodicalIF":0.7,"publicationDate":"2026-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148927667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
