These alloys, denoted as P91 (B=0, N=330 ppm), P91B (B=100 and N=20 ppm) and P91BN (B=60 and N=110 ppm), underwent exposure to varying concentrations of NaOH (0.1, 0.2 and 0.5 M) solutions. Additionally, the study explored the influence of chloride (0.1 M NaCl) on the occurrence of pitting corrosion within an alkali environment. The results indicated that the passive current density in all the concentrations of NaOH studied is maximum for alloy P91 followed by P91B and P91BN, respectively, indicating alloy P91 is more prone to corrosion than alloy P91B and P91BN. Electrochemical impedance spectroscopy demonstrated a higher polarisation resistance value for P91BN and the lowest for P91. Scanning electron microscopy analysis revealed that in alloy P91B and P91BN, pits are formed at the M23C6 carbide/matrix interface whereas in alloy P91 apart from carbides, pits are formed at inclusions. Energy-dispersive X-ray mapping identified the elemental composition of the inclusion in P91 which is found to be complex Al2O3–MnS inclusions enriched with Mo. P91BN demonstrated better pitting corrosion resistance compared to alloys P91 and P91B when exposed to NaOH+NaCl medium.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"360 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141006682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under specific conditions, CO2 corrosion occurs at the top section of the pipeline, which is known as top-of-the-line corrosion (TLC). TLC tests were conducted in the water-hydrocarbon co-condensation environment using 10 vol% n-heptane and 25 vol% n-heptane to simulate the internal condition of a wet gas pipeline to study the effect of hydrocarbon volume ratio towards TLC. The presence of n-heptane showed minimal effect on the gas temperature profile; however, n-heptane suppressed the water condensation, resulting in a tremendous decrease in the water condensation rate (WCR). The TLC rates were found to be lower in the presence of n-heptane, which can be attributed to the reduced WCR and water-wetted areas. The presence of n-heptane had no significant effect on the pitting rates but showed an increasing pit ratio as the n-heptane volume increased. TLC tests were conducted at three durations: one day, two days and three days showing that n-heptane has no significant effect on corrosion kinetics.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"35 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141022774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As the most promising third-generation medical β-type titanium alloy, Ti-13Nb-13Zr (TC26) demonstrates superior corrosion resistance and harmless chemical element composition, making it an excellent alternative to Ti-6Al-4V alloy (TC4). Nonetheless, this study has revealed a significant weakness of TC26 in tribocorrosion properties under low dissolved oxygen concentration conditions, which could pose potential hazards in subsequent medical applications. The effects of low dissolved oxygen concentration on the tribocorrosion properties and ion release were examined using electrochemical methods, laser confocal microscopy, scanning electron microscopy, and inductively coupled plasma emission spectrometer. The findings indicate that TC26 exhibits significantly inferior corrosion resistance compared to TC4 due to the sluggish recovery rate of the passivation film under low dissolved oxygen concentration conditions during wear. Moreover, TC26 experiences greater mechanical wear loss than that of TC4. However, under the synergistic effect of wear and corrosion, TC26 releases a minimal amount of ions, while excessive harmful Al ions are released by TC4.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":" 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140692841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Climate change has the potential to alter the long-term characteristics of these factors over the lifespan of steel structures, both those already existing and those newly built. The impact of climate variability on the stochastic nature of atmospheric variables, which greatly influence corrosion conditions, can add complexity to corrosion predictions in these structures. This paper introduces an integrated framework to quantify the impact of climate change on corrosion rates of steel structures worldwide. It considers the changes in environmental conditions, specifically temperature, relative humidity and wind speed and their effects on atmospheric corrosion. Global Climate Models are employed to evaluate the long-term impacts of climate change on these environmental conditions. An analytical model for predicting corrosion rate is integrated with climate change models to predict alterations in the corrosion rates of steel components relative to historical conditions. This paper also discusses the impact of climate change on the variations of these climatic parameters and offers a comparison between historical data and projected conditions across the globe. The results indicate that the effect of climate change on the corrosion rate depends on the considered region. While regions such as Australia, North America and Europe see an increase, others such as Asia and Africa observe a decline. Notably, all oceans, especially the Antarctic and Arctic, experience a significant increase in corrosion by the end of the century.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"44 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140373568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption process's thermodynamic parameters (ΔH*, ΔS* and Ea) were determined and explained. The inhibitor was examined as a mixed-type (anodic and cathodic) inhibitor based on polarisation studies. The inhibitor, according to the SEM data, is partially coating the metal surface, providing it with a reasonable amount of protection.

Plasma electrolytic oxidation (PEO) is used to create the coating, and the surface properties are analysed using X-ray diffraction (XRD), atomic force microscopy (AFM) and field-emission scanning electron microscopy (FE-SEM). Contact angle measurements adapted to compare the uncoated substrate (144.74 ± 2.08°) with the coated substrates, which exhibit contact angles of (107.92 ± 2.16°), (95.88 ± 2.06°) and (66.05 ± 2.09°) for the respective coating durations. Increasing the thickness of the coating improves its corrosion resistance. Specifically, a 6-minute PEO coating significantly increases the thickness and provides better protection against corrosion for the AZ31B magnesium alloy. Cross-sectional scans of the coated samples revealed an increase in specimen thickness from 32.92 μm to77.17 μm. Potentiodynamic polarisation tests in a simulated body fluid reveal that the 6-minute coated sample shows the highest corrosion resistance, with the lowest corrosion current density (1.9037 × 10-06) compared to other coatings, indicating strong protection against corrosion. This research proposes a novel method to enhance the corrosion resistance of PEO coatings on magnesium alloys by depositing a thicker layer of hydroxyapatite, anatase TiO2 and CeO2. This approach results in a stronger and more effective protective system against corrosion.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"12 s1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140222173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim was to determine the effect of temperature, presence of chloride ions, degradation of the aMDEA and amount of dissolved oxygen on the corrosion resistance of these materials. The results indicated that raising the temperature between 50 and 120°C led to a higher corrosion rate of both CS and 304 SS. However, the corrosion rate of 304 SS decreased and remained stable at higher temperatures as the corrosion reaction became mass-controlled. Oxygen loading results in the passivation of both CS and 304 SS. The amine degradation products were found to accelerate the corrosion rate of CS at 50°C due to a chelation effect of iron ions, and also increase the corrosion rate of 304 SS at 120°C by causing the passive film rupture. The SCC test on U-shaped 304 SS samples showed transversal microcracks with a depth of more than 25 µm after 2 months of immersion in an autoclave containing CO2-saturated aMDEA at 120°C, which confirmed the SCC risk of 304 SS.","PeriodicalId":517061,"journal":{"name":"Corrosion Engineering, Science and Technology: The International Journal of Corrosion Processes and Corrosion Control","volume":"258 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140233411","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
