A two-phase structure consisting of an Al(Co) solid solution and cobalt aluminide forms in all samples independent of applied pressure. As the melt solidifies under high pressure, the structure is substantially denser and finer with a higher (by a factor of ~1.1–1.4) microhardness as compared to the sample prepared at normal atmospheric pressure. At pressures higher than 5 GPa, the solidification mechanism changes: the initially hypereutectic alloy solidifies as a hypoeutectic alloy. In this case, an anomalously supersaturated Al(Co) solid solution forms: the cobalt content in aluminum exceeds the equilibrium value by a factor of 100 and is ~3 at % at pressure of 10 GPa. The alloys Al97Co3, Al96Co4, Al94Co6, and Al93Co7 solidify according to the same mechanism as Al95Co5 alloy does; in this case, the quantitative proportions of the structural components (α-Al, α-Al + Al9Co2 eutectic) in the alloys change.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 8","pages":"1638 - 1647"},"PeriodicalIF":0.3,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145898402","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 thermal stability of the synthesized materials and their chemical resistance toward each other are investigated. For this purpose, mixtures of the solid electrolyte and the bronze are held for 15 h at various temperatures from room temperature to 500°C, and their phase compositions are then studied by X-ray diffraction (XRD). XRD shows no chemical interaction between the electrolyte and the bronze up to 300°C inclusive. At higher temperatures (350°C), reflections of lithium metavanadate first appear on X-ray diffraction patterns; after isothermal holding at 470–500°C, the phase compositions of the mixtures include a number of interaction products, the main of which is Li2PVO6. Thus, according to the obtained results, the materials under study can be recommended as components for the development of medium-temperature all-solid-state lithium-ion batteries.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 7","pages":"1539 - 1544"},"PeriodicalIF":0.3,"publicationDate":"2026-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145898542","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}

Here, we substantiate the possibility of using supersonic flame spraying to create protective coatings on machine parts for various functional purposes. The characteristics of the coatings are determined and compared; they demonstrate the advantages of this method compared to subsonic gas-thermal coating formation methods. The aim of this work is to study the physical and mechanical properties of coatings formed by high-velocity flame spraying under various conditions. The coatings are deposited onto samples using the Plakart-HV2 robotic complex for high-velocity flame (HVOF) spraying. WC–Co–Cr 86-10-4 and PR‑Kh14N7S3R3 powder materials are used to form the coatings. Metallographic examination of the sprayed coatings is carried out according to generally accepted methods. Dense, wear-resistant coatings with a maximum hardness of 1475 HV are found to be formed from the WC–Co–Cr 86-10-4 powder by supersonic flame spraying under rational conditions. The high microhardness of the coatings made from this powder mixture is caused by the presence of WC in their structure. When the PR-Kh14N7S3R3 powder material is used, the maximum microhardness is about 927 HV. The properties of the coatings produced by supersonic flame spraying depend on the powder material composition and their formation conditions. The characteristics of the formed layers can be changed over a wide range by varying the process conditions and the content of elements in the sprayed powder material, which enables the production of coatings with the required physical and mechanical properties.","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2025 6","pages":"1485 - 1489"},"PeriodicalIF":0.3,"publicationDate":"2025-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145824405","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}
