Consequently, enhancing the corrosion resistance of Mg alloys is an urgent issue that necessitates immediate attention in their applications. Polytetrafluoroethylene (PTFE), often termed the ‘king of plastics’ because of its exceptional chemical inertness and non-reactivity, forms coatings that effectively shield metal substrates from corrosive environments. This capability substantially reduces corrosion rates, underscoring its considerable potential in corrosion prevention. In this study, PTFE coatings were successfully prepared on Mg–3Al–1Zn (AZ31) alloy sheets through electrophoretic deposition (EPD). The coatings underwent sintering treatments of varying durations, and their corrosion resistance properties were systematically evaluated. The results indicate that sintering duration critically influences the microstructural morphology of the PTFE coatings; extending the sintering duration within a specific range enhances the microstructure’s compactness. Furthermore, the study examined the corrosion behavior of Mg alloys coated with sintered PTFE in a 3.5 wt % NaCl solution, where the corrosion resistance of the sintered PTFE-coated AZ31 was significantly enhanced. Notably, coatings sintered for 14 h exhibited the highest corrosion resistance, with the corrosion current density decreasing from 4.05 × 10–5 A cm–2 for the bare AZ31 to 1.20 × 10–7 A cm–2 for the sintered PTFE-coated AZ31. Concurrently, the charge transfer resistance increased significantly from 227 to 2.72 × 105 Ω cm2. The coatings achieved a contact angle exceeding 123° and an adhesion rating of 5B. This offers a novel approach for mitigating corrosion in Mg and its alloys.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"60 6","pages":"1120 - 1135"},"PeriodicalIF":1.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698568","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}

A powder embedding technique at 900°C with 60 wt % aluminum was employed to prepare the coating. The phase composition and surface morphology of oxidation products were analyzed using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Untreated and aluminized samples were subjected to oxidation at 800, 900, and 1000°C for 100 h. Post-treatment, the GH3039 alloy exhibited a uniformly distributed aluminized layer about 90 μm thick. This layer comprised three distinct sub-layers: a top layer with Ni2Al3 and minor NiAl3 phases, a middle layer of mainly Ni2Al3, and a β-NiAl phase-rich bottom layer. Oxide weight measurements indicated an initial rapid increase followed by a significant reduction at high temperatures, primarily due to Cr2O3 volatilization into gaseous CrO3. Oxidation curves for the aluminized samples showed reduced and stable weight gain patterns, adhering mostly to the parabolic law with no further increase at advanced stages. The untreated samples presented a porous oxide film with complex components including Cr2O3, NiCr2O4, TiO2, which adversely affected their oxidation resistance. In contrast, the aluminized samples predominantly displayed an Al2O3 film that transitioned from flaky θ-Al2O3 to a compact α-Al2O3 structure at increased temperatures, thereby significantly enhancing the alloy’s resistance against high-temperature oxidation.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"60 6","pages":"1136 - 1146"},"PeriodicalIF":1.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698569","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 electrical conductivity of the samples was investigated by measuring area specific resistance. The results showed that the weight gain of uncoated and Mn–Co–Y2O3-coated samples after isothermal oxidation for 500 h was 0.52 and 0.4 mg cm–2, respectively. Microscopic investigations demonstrated that a non-continuous thin oxide scale forms underneath the applied coating, while high outward diffusion of Fe, Mn, and Cr occurred in uncoated steel after 500 h of oxidation at 800°C.

The –∆H* values support an exothermic process and –∆S* values confirm TIF adsorbed on mild steel surface. The –∆G° values reveal that the TIF adsorption on mild steel is a spontaneous process. Mixed type inhibition behavior was confirmed by Tafel plots.

MMA provides rigidity and durability, while BA imparts flexibility to the polymer. To enhance its antibacterial capabilities, the acrylic emulsion was polymerized in-situ using 1.5% (relative to the monomers) magnesium oxide (MgO) nanoparticles. In-situ polymerization helps in the uniform dispersion of nanoparticles within the polymer matrix, enhancing the properties of the final product. The synthesised acrylic emulsion was evaluated using Fourier-transform infrared (FTIR) spectroscopy to determine its structural characteristics, an E. coli test to determine its antibacterial qualities and a Brookfield viscometer to determine its viscosity. The prepared acrylic emulsions were applied as a coating on mild steel (MS) panels and tested for its adherence, gloss, drying time, and flexibility. The study demonstrates that MgO nanoparticles can effectively enhance the antimicrobial properties of acrylic emulsions without compromising other essential coating properties like gloss, adhesion, and flexibility, making them suitable for protective coatings in various applications.","PeriodicalId":745,"journal":{"name":"Protection of Metals and Physical Chemistry of Surfaces","volume":"60 6","pages":"1069 - 1076"},"PeriodicalIF":1.1,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698453","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}
