Three types of hydrogen bonds have been identified: (‒CO…H2O…CO–) (III) type ~30 kJ/mol, H2O…HN (II) type ~16 kJ/mol, and (I) type ~9 kJ/mol. Sorption water in a water-saturated sample, reducing the energy of intermolecular (NH…O=C) bonds, changes the configuration of PA6 macromolecules without changing the trans-conformers. At the same time, FTIR spectrum of the working membrane sample (absence of absorption band at 1478 cm–1) shows breaking of H‑bonds, accompanying changes in the configurations of molecules with increasing gauche conformers. Manifestation of a complex absorption band at ~1723 and 1737 cm–1, attributed to terminal carboxyl groups (COOH), indicates the destruction of PA6 macromolecules. Disappearance of the absorption band at ~3089 cm–1 for the first time experimentally confirms the connection between the Fermi resonance phenomenon in polymer molecules and the destruction of PA6 macromolecules to elementary structural units. X-ray studies indicate structural changes mainly at the supramolecular level in MMK-045 membrane samples. In a water-saturated sample, the density of molecules in the amorphous phase increases (2θ = 26.4°), and in the working one it decreases (2θ = 20.9°). The total crystallinity in the working membrane sample relative to the nonworking one decreased from 36 to 33%, not as a result of recrystallization, but rather as a result of a reduction in crystallites of α-phases, and increased in crystalline formations of γ-phases with imperfect crystalline structure.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"60 4","pages":"585 - 594"},"PeriodicalIF":1.1,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438656","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}

The methods carried out by using open circuit potential (OCP), electrochemical impedance spectroscopy (EIS), potential-current (Tafel) and linear polarization resistance (LPR) techniques in the AOS. In the previous study, α-pinene showed significant anti-corrosion capacity in CA medium by increasing the concentration of hydrogen ions. The aim of this research is to reveal the synergistic effect of the α-pinene and CA compounds on the material. Electrochemical results revealed that α-pinene played a role in the synergistic effect and acted as an excellent corrosion inhibitor. This effect shifted the pH of the solution from 5.20 to 5.60 on the basic side, also corrosion potential (Ecorr) shifted by 158 mV from –0.412 to –0.254 V towards the anode. Therefore, corrosion resistance (Rp) significantly increased from 50 to 254 kΩ cm2 (80%). Results indicated that TiO2 layer formation supported by α-pinene in this conditions. ICP-MS analysis also confirmed the formation of this layer. DFT study carried out by using different methods on the Gaussian 09W with 6-311G (d, p) basis set for α-pinene on cp-Ti.

The investigation involved several tests, including microhardness tests, intergranular corrosion performance tests, metallographic analysis, and electrochemical analysis. The results reveal that rolling deformation alters the microstructure of GNP/2024Al composites. Specifically, increasing rolling deformation leads to the distribution of grains along the rolling direction, the aspect ratio becomes larger, and the grain becomes slender. At 20% rolling deformation, the composite’s hardness improves, but at 40 and 55% deformation, the hardness decreases slightly. However, the overall range of hardness changes is small. As the deformation increases, the fibrous structure becomes more slender, leading to more grain boundaries per unit area. Additionally, the hot rolling process presses some microstructural defects that affect corrosion together, reducing such defects in the microstructure. The corrosion current density of the GNP/2024Al composites initially increases and then decreases with increasing rolling deformation, while the intergranular corrosion resistance decreases and then increases. Finally, the microscopic mechanism behind these observations is discussed.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"60 4","pages":"734 - 742"},"PeriodicalIF":1.1,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143438617","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}
