The variation of the concentration–time hydrogenation annealing parameters is shown to control the hydrogen penetration depth and a surface layer structure. Subsequent low-temperature vacuum annealing makes it possible to transform a coarse lamellar structure into a fine structure with a hardness of 40 HRC. The thickness of a layer with a fine structure after unidirectional hydrogenation with a barrier coating is found to be twice as large as that after volumetric nonequilibrium hydrogenation in the absence of the coating.</p>","PeriodicalId":769,"journal":{"name":"Russian Metallurgy (Metally)","volume":"2024 5","pages":"1091 - 1096"},"PeriodicalIF":0.4000,"publicationDate":"2025-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":"0","resultStr":null,"platform":"Semanticscholar","paperid":null,"PeriodicalName":"Russian Metallurgy (Metally)","FirstCategoryId":"5","ListUrlMain":"https://link.springer.com/article/10.1134/S0036029524702069","RegionNum":0,"RegionCategory":null,"ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":null,"EPubDate":"","PubModel":"","JCR":"Q4","JCRName":"METALLURGY & METALLURGICAL ENGINEERING","Score":null,"Total":0}
