Furthermore, no prior studies have investigated plasma treatments applied to HSX 130HD XTP® steel, which undergoes microstructural refinement through thermomechanical post-processing. This study evaluates the effects of plasma nitriding and nitrocarburizing on two bainitic steels, HSX 130HD and HSX 130HD XTP® (Xtreme Performance Technology®), with a focus on microstructural evolution, microhardness, phase formation, and wear resistance. Although both steels share the same chemical composition, the HSX 130HD XTP® variant exhibits a finer microstructure due to its thermomechanical processing. Plasma treatments were conducted using different gas mixtures, specifically N₂ (fixed at 75 vol%), H₂ (balance), and CH₄ (3 vol% and 5 vol%), at 500 °C for 6 h. The resulting microstructure, roughness, surface and profile microhardness, phase composition (determined via X-ray diffraction), friction coefficient under dry sliding, and wear resistance (evaluated through reciprocating sliding wear tests) were analyzed. The results indicate that increasing CH₄ concentration led to a reduction in white layer thickness, an increase in surface microhardness and roughness, and enhanced Fe₂-₃N phase formation for both substrates. Fe₃C formation was also observed in HSX 130HD XTP® samples treated with 5 vol% CH₄, while a lower friction coefficient was recorded for the same steel treated with 3 vol% CH₄. Although plasma nitrocarburizing proved to be effective for both steels, plasma-nitrided HSX 130HD XTP® exhibited the lowest worn volume, highlighting its superior wear resistance.</div></div>","PeriodicalId":22009,"journal":{"name":"Surface & Coatings Technology","volume":"504 ","pages":"Article 132028"},"PeriodicalIF":5.3,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143619929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
