The values of the billet temperature were determined for the calculated moments of the passage of the billet through the junction of the die channels, which corresponded to 25, 50, and 75% of its length. During the ECAP process at a given pressing speed, in the section corresponding to the junction of the matrix channels, an increase in the billet temperature relative to its initial heating occurred by an amount of approximately 10°C.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 1","pages":"63 - 74"},"PeriodicalIF":0.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100340","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}

Attempts to experimentally verify the correctness of the criterion of electrohydrodynamic instability of a highly charged drop, the Rayleigh criterion, which began in the middle of the last century and continue to the present, confirm it but with some error that does not decrease over the years (with the improvement of the instrument base), which indicates the principle of such an error. In general, the need to position the droplet implies the influence of certain external fields that deform the droplet and, thereby, affect the accuracy of the determined Rayleigh criterion. An experimental and numerical study of the instability of an uncharged drop in an external electrostatic field, the Taylor drop instability, shows its qualitative similarity to the instability of a charged Rayleigh drop. Somewhat apart is the electrohydrodynamic instability of the flat surface of the liquid, the Tonks–Frenkel instability, well studied theoretically but poorly experimentally, due to the fact that high-speed movie cameras have relatively recently entered scientific use.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 1","pages":"34 - 54"},"PeriodicalIF":0.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100342","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}

This study aimed to impart wear resistance for the cutting tools while increasing cutting power and reducing the coefficient of friction, especially for machining hard-to-cut materials like D2 tool steels. This investigation examined the influence of laser surface modification with thin film bionic micro textures and tungsten deposition on the rake surface of the tungsten carbide uncoated cutting tools to reduce friction and wear. This study describes a unique material texturing method inspired by the surface morphology of dung beetle bionic zigzag patterns engineered on the substrates of cutting tools. In the dry cutting trials, an improvement in the machining performance and service life of the cutting tools was observed, which was attributed to the synergistic effect of surface textures and modification of the chemical composition of the rake surface of the cutting tools. The combined features of the dimple and mesh pattern provide a robust surface with high hardness, improved wear resistance, and the potential for reduced friction. A 24.47% decrease in the coefficient of friction was observed after the computer numerical control machining of textured inserts, leading to a reduction in tool wear and an increase in tool life. The technique helps to tailor surface characteristics for various metal-cutting tools and can also be extended for surface modification of mechanical implements in agricultural applications.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 1","pages":"81 - 105"},"PeriodicalIF":0.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100341","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 calculations took into account the following factors: electrochemical reactions, electromigration of ions in the potential gradient field, diffusion through the membrane that separates the cathode and anode chambers, change in the volume of the solution due to the water molecules compaction in the hydration shells of ions, and change in alkali concentration. The electrolysis mode consists of two consecutive current pulses: the first-cathodic and the next-anodic. Theoretical calculations of the system state in the two-pulse mode are the most accurate since the chemical composition of the electrolyte does not change at the moment of switching the current. However, the directions of electrode reactions, electromigration, and electroosmosis change. In the electrolysis mode with more pulses, it would be impossible to calculate the state parameters. A mathematical model has been created for a comparative analysis of the influence of different electrolysis conditions on the speed ratio of various processes.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 1","pages":"24 - 33"},"PeriodicalIF":0.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100280","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 mechanism substantiating the manifestation of the skin effect in the specified conductor is based on the Faraday–Maxwell law of electromagnetic induction. It is mathematically shown that the induction alternating conduction currents and their alternating magnetic fields arising in the conductor material under the action of the alternating conduction current i0(t) and, accordingly, under the action of the intrinsic alternating magnetic flux Ф0(t) at dФ0(t)/dt > 0 weaken the intensities of the intrinsic alternating EMF distributed inside the conductor and, at dФ0(t)/dt < 0 maintain the EMF intensities decreasing with time and across the depth of the conductor material.","PeriodicalId":782,"journal":{"name":"Surface Engineering and Applied Electrochemistry","volume":"61 1","pages":"55 - 62"},"PeriodicalIF":0.9,"publicationDate":"2025-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100327","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}
