This study aims to develop a composite coating with integrated functions of corrosion resistance and hydrogen barrier. Firstly, a dense black oxide layer was chemically formed on X65 pipeline steel at room temperature by a modified blackening process. Then, the traditional epoxy resin was applied onto the surface of black oxide layer, obtaining a novel black oxide/epoxy resin composite coating. For the blackening process, the effects of surface pretreatment methods (untreated, polished, sandblasted) and blackening solution pH (1.5, 2.5, 3.5) on the microstructure, corrosion resistance and hydrogen barrier performance were investigated, as well as the adhesion strength of composite coating. Results show that corrosion resistance and hydrogen barrier performance of coatings depended on both blackening solution pH and pretreatment method, with polished substrates and pH 2.5 yielding optimal results. Additionally, the black oxide layer served as an effective adhesion-promoting interlayer, enhancing the bonding and durability of the composite coating. This novel black oxide/epoxy composite coating system offers valuable insights for designing hydrogen barrier coatings for pipeline steels.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 2","pages":"344 - 352"},"PeriodicalIF":1.1,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thorough spectral characterization was conducted on both the ligand and its respective metal complexes. Infrared spectroscopy, energy-dispersive X-ray spectroscopy (EDS), and elemental analysis were employed to confirm the successful synthesis of the complexes and accurately identify their constituent elements. The stability of the metal-ligand complex was evaluated through thermogravimetric analysis (TGA). Additionally, fractal analysis was performed on the ligand lanthanide (III) complex. The cube counting method revealed that the fractal dimension (Df) value followed the order of La > Ce > Yb, indicating that lanthanum exhibited the highest surface roughness. Consequently, La demonstrated the greatest antibacterial and antifungal properties, attributable to its rough surface. The enhanced biological activity of the La(III) complexes can be attributed to the presence of surface roughness. Furthermore, due to the structural modification of the metal complexes into nanostructures, the antimicrobial activities exhibited by the metal complexes surpassed those of the ligands. Notably, the La(III) nanosized complex displayed excellent antimicrobial activity.

Although SRB have been extensively studied in reservoirs and produced waters, oil-contaminated soils remain insufficiently investigated despite their potential to serve as long-term microbial sources of sulfide and corrosion activity. This study investigates the occurrence, abundance, metabolic activity, and corrosion-related effects of sulfate-reducing bacteria in oil-contaminated soil samples collected from the Bibi-Heybat OGPD. Soil samples were enriched and cultivated under anaerobic conditions using selective Postgate B medium. SRB abundance was determined by culture-based methods, sulfide production was quantified iodometrically, and the corrosive aggressiveness of soil-derived aqueous extracts was evaluated gravimetrically using carbon steel coupons. Molecular identification of representative isolates was carried out by partial 16S rRNA gene sequencing. The results demonstrated significant SRB populations ranging from 104 to 106 cells g–1 dry soil, with Desulfovibrio species dominating the microbial community. Active sulfate reduction was confirmed by sulfide accumulation reaching approximately 400 mg L–1 after 7 days of incubation. Higher SRB abundance was associated with slightly alkaline soil pH and increased corrosion rates, indicating that oil-contaminated soils represent an important and previously underestimated corrosion risk factor in oilfield environments. The obtained results contribute to understanding the microbial diversity and corrosion potential of subsurface environments associated with offshore oil extraction.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 2","pages":"424 - 434"},"PeriodicalIF":1.1,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856704","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article wants to investigate the hydrogen storage increase through doping of Cr, Ni, Zn, Mo, Pd, Cd on the boron nitride nanocage. Based on NQR analysis, nickel, and palladium with atomic charges of 0.2658 and 0.3266 C on the complexes of Ni@BN and Pd@BN, respectively, have shown much more tendency for H2 adsorption than other complexes. The results of NMR spectroscopy have exhibited that the efficiency of electron admitting for implanting atoms on the [Cr, Ni, Zn, Mo, Pd, Cd]@BN through H2 adsorption can be ordered as: Ni > Pd ( gg ) Cr > Mo ≈ Zn > Cd. Regarding thermodynamic properties, it was indicated that for hydrogen sites in H2 molecules, the consistencies of heteroclusters of decorated elements of Cr, Ni, Zn, Mo, Pd, Cd can be brought up as: Ni@BN > Pd@BN ( gg ) Cr@BN > Mo@BN ≈ Zn@BN > Cd@BN complexes. In addition, the hydrogen adsorption on transition metals doping BN heterocluster has been estimated through density of states analysis of total density of state (TDOS), partial density of states (PDOS), overlap partial density of states (OPDOS) and localized orbital locator analysis (LOL). Thus, the transition metal implanted BN can be used for designing novel materials for H2 adsorption and sensing applications. Strong hybridization between the d orbitals of TM and the sp orbitals of boron exists in a family of six TM–boron intermatallics (TM@B), and hydrogen atoms adsorb more weakly to the metal-terminated intermetallic surfaces than to the corresponding pure metal surfaces.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"62 2","pages":"265 - 280"},"PeriodicalIF":1.1,"publicationDate":"2026-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148856703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
