Based on an analysis of retrospective information about market concentration and liquid steel production indicators in the Top-10 countries, as well as the gross domestic product of these states from 2009 to 2023, we obtained data to evaluate the potential development opportunities for business in the metallurgical sector of both the domestic and global economy. Estimated indicators of competitive relations in the Russian steel production sector have been established. They correspond to production in the Top-10 countries according to direct competition measures, i.e., absolute entropy, and indirect ones, such as the Herfindahl–Hirschman index, for the years 2009–2023. A general trend toward monopolization in the production and economic sphere of the metallurgical sector of the global economy is identified, and the prospects for positive positioning of the domestic steel cluster in the global development of metallurgy are evaluated.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 1","pages":"235 - 240"},"PeriodicalIF":0.3,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144909779","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}

A clear technique is necessary for choosing materials, equipment, and tools, the sequence and description of operations, and technological parameters (modes) that influence the properties and quality of the coatings produced by this method. To develop a technique for producing, strengthening, and restoring machine parts, functional ECW coatings are studied using a 011-1-10 Remdetal setup. The welding pulse and pause durations are set using an RVI-501 controller. The welding current is calibrated using a 5-mm-thick MM copper strip and an IST-02 welding current meter. An analysis of the electrical resistance of the ECW joint zone shows that the optimum compression force of welding electrodes on a 65G steel plowshare is 1.7 kN for a U12 steel tape. To ensure the maximum process efficiency and complete overlap of weld spots (accounting for the relative movement of electrodes and the part), dependences are derived to determine the following main ECW parameters for all schemes and equipment options: welding current, pulse duration and pause time, electrode compression force, welding speed, weld spot overlap coefficients, and cooling fluid flow rate. Their influence on the process and the coating quality is discussed. The proposed algorithm for calculating and setting welding parameters simplifies the application of the technology and improves the coating quality by minimizing defects caused by parameter errors. The algorithm can be used in machine-building and repair production for designing processes to produce functional coatings for hardening and restoring machine parts.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 1","pages":"180 - 185"},"PeriodicalIF":0.3,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144909896","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}

These materials are produced using special powder wire deposition technology. The machining of these parts encounters significant challenges. Grinding is not an option for several technical reasons, and metal cutting with end mills and face mills is required. Currently, there are no systematic guidelines available for this machining process, and there are no recommendations for maintaining optimal cutting system conditions. This work investigates face milling characteristics for such coatings using mechanically clamped carbide inserts. The aim of this work is to maintain optimal performance of the machine–fixture–tool–workpiece cutting system during milling of high-hardness parts to enhance the operational efficiency of the metal-cutting tool. Research objective. (1) To enhance the cutting tool performance. (2) To develop the criteria for assessing and controlling the current condition of the cutting system. (3) To predict the cutting system condition and maintain its optimal performance. Research techniques. Experimental analysis, computational modeling, and acoustic emission monitoring are used. Novelty. The scientific novelty of this work is (1) in establishing criteria for real-time assessment of the cutting system current state, and (2) a predictive methodology that enables both forecasting the cutting system state and controlling its operational parameters. Results. The feasibility of highly efficient milling of high-hardness materials while meeting the three critical requirements of machining productivity, surface finish quality and carbide insert life is shown. Conclusions. The criteria developed for the estimation of the cutting system state provide real-time process control while maintaining the required workpiece surface quality, machining productivity, and tool life.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 13","pages":"2014 - 2017"},"PeriodicalIF":0.3,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145160561","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}
