Abstract Replacing or servicing corroded reinforced concrete structures requires careful consideration of the rate of corrosion of the embedded rebar. Corrosion rates are usually measured using monitoring techniques, but these techniques may not always give reliable results due to the effect of factors called rate influencers. Though the consideration of rate influencers does not entirely alleviate the problem, monitoring them during measurements will significantly reduce the probable error. Hence, this paper compares the experimental results of prior studies with an effort to draw out the best corrosive environment for the efficient working of a few widely used monitoring techniques and presents a list of some major rate influencers that need concern for the accurate evaluation of corrosion. A literature review is performed to achieve the above objectives. The Monitoring techniques considered in this study are linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS), galvanostatic pulse technique (GPT), and half-cell potential (HCP).

Abstract Graphene and its derivatives have attracted much interest as corrosion-resistant coatings for magnesium alloys since 2014, when the first reports appeared in the literature. The interest in the use of such carbonaceous compounds to protect magnesium and its alloys from corrosion relies on a set of attributes such as chemical inertness, and high surface area. To support the development of optimized graphene-based films it is imperative to expand the current knowledge toward a deeper understanding of corrosion mechanisms and their interaction with practical aspects related to coating deposition and morphology. In the present work, graphene-based coatings for magnesium alloys are reviewed. We explored the correlation between coating architecture, deposition methods and materials selection using the Ashby approach. The results of the materials selection process revealed that composite coatings consisting of an inorganic matrix obtained by plasma electrolytic oxidation of magnesium alloys and graphene oxide nanosheets as blocking agents can provide surfaces with high corrosion resistance in sodium chloride solution. For biomedical applications, composite coatings consisting of a mixture of organic matrices such as chitosan and graphene oxide as reinforcing particles are attractive candidates. The results are discussed based on coating architecture and its interplay with the corrosion properties.

Abstract The study of a stir cast Al356-Nb2O5)P composite immersed in third-generation microalgal-derived biodiesel blends with enhanced plasma electrolyte oxidation surface modification revealed the corrosion susceptibility and possible by-product formation. The effect of (oxide)P reinforcement and mixed-oxide surface coatings were studied separately and cumulatively. Samples were immersed in different biodiesel and petrodiesel blends for up to 3000 h, and their corrosion and electrochemical behavior was studied. Although some weight change was recorded in all samples, the corrosion rates significantly decreased from 1.8 to 1.3 by 10 wt% Nb2O5)P reinforcement, which further decreased 10 times after surface modification. Electron microscopy revealed primary fine-grained microstructure with low porosity content of fine and needlelike dendritic structures in composites and irregular volcanic with scattered micropores and microcracks in surface-modified composites that changed to corrosion spots and flake-covered microcracks after immersion.

Abstract An epoxy with 7% polyaniline (PANI) powder coating by electrostatic deposition is proposed to enhance the corrosion resistance of AZ61 magnesium alloys. The coating thickness is varied from 85 to 130 microns, and the results are compared to the corrosion resistance of epoxy coated and uncoated AZ61 magnesium alloy. The surface characterization and corrosion behaviour of AZ61 magnesium alloy + epoxy/PANI coating are examined using X-ray photoelectron spectroscopy, salt spray test, potentiodynamic test and Fourier transform infrared spectroscopy. It is observed that the polymer coating protects the base metal against corrosion and the corrosion resistance increases with coating thickness. The corrosion rate of the uncoated, 130 µm coating thickness of epoxy coated and epoxy/PANI coated AZ magnesium alloy is observed to be 0.5379, 0.0869 and 0.0372 mm/year, respectively. The corrosion resistance of epoxy/PANI coating is superior to the epoxy coating. The increase in corrosion resistance of the epoxy/PANI coated AZ61 alloy is attributed to the physical insulation and suppression of magnesium dissolution.

Abstract Coatings of metal surfaces is a convenient and low cost anti-corrosion issue, while corresponding defects like poor heat and corrosion resistance are also obviously hinder its further application. Hence, continuously developing new and efficient coatings is of great significance to improve anti-corrosion for metals. In this study, silicone-acrylic resin was modified by two-dimensional lamellar structure of graphene oxide (GO) though direct co-blending to improve the anti-corrosion. Then, polyaniline/graphene oxide (PANI/GO) composites was prepared by in-situ polymerization method, which innovatively achieved the combination of flake and fibrous materials to fill the voids generated when the coating is cured into a film, and enhance the density and the anti-corrosion performance of the coating. The result showed that the coating modified by PANI/GO had the better thermal stability, which T5% and Tmax are increased by 44 and 5 °C, respectively. Electrochemical impedance spectroscopy (EIS) and Tafel polarization curves were employed to analyze anticorrosion performance of modified coatings explored in 3.5 wt% NaCl aqueous solution. The coating with 20 wt% GO in PANI/GO has the best corrosion resistance with corrosion potential of −0.14 (V vs. Hg/Hg2Cl2), corrosion current density of 1.8 × 10−11 A cm−2, polarization resistance of 6.06 × 1010 Ω cm2, and lower corrosion rate of 4.18 × 10−7 mm year−1 after immersion for 60 day.
摘要金属表面涂层是一种方便、低成本的防腐问题，而相应的耐热性和耐腐蚀性差等缺陷也明显阻碍了其进一步应用。因此，不断开发新型高效涂料对提高金属的防腐性能具有重要意义。本研究采用氧化石墨烯（GO）的二维层状结构，通过直接共混的方式对硅丙树脂进行改性，以提高其耐腐蚀性。然后，采用原位聚合法制备了聚苯胺/氧化石墨烯（PANI/GO）复合材料，创新性地实现了片状和纤维状材料的结合，填补了涂层固化成膜时产生的空隙，提高了涂层的密度和防腐性能。结果表明，PANI/GO改性的涂层具有较好的热稳定性，其T5%和Tmax分别提高了44和5°C。采用电化学阻抗谱（EIS）和Tafel极化曲线分析了改性涂层在3.5wt%NaCl水溶液中的防腐性能。PANI/GO中含有20wt%GO的涂层具有最佳的耐腐蚀性，浸渍60天后的腐蚀电位为−0.14（V vs.Hg/Hg2Cl2），腐蚀电流密度为1.8×10−11 A cm−2，极化电阻为6.06×1010Ωcm2，腐蚀速率较低，为4.18×10−7 mm year−1。

Abstract The review article summarizes various ionic liquids (ILs) used as corrosion inhibitors reported in the literature during the preceding five years (2016–2020) for corrosion of carbon steel in acidic solutions. The ILs are a green and sustainable choice for corrosion inhibition as compared to natural extracts as corrosion inhibitors due to lack of stability which restricts their application at the industrial level. The review discusses the inhibition efficiency of the ILs as corrosion inhibitors; the evaluation techniques like weight-loss method, potentiodynamic polarization, electrochemical impedance spectroscopy, etc., used for determination of inhibition efficiency and plausible mechanism of inhibition, adsorption isotherms are discussed. The review affirms that ionic liquids serve as excellent green corrosion inhibitors for carbon steel dissolution in acidic media. Most of the reported inhibition efficiency values ranged between 80 to 90% at minute concentrations which is valuable. The scope for further improvements is given for the benefit of readers.

Abstract The corrosion characteristics of newly synthesized (ATOMET 4601 + 2%TiC) high strength alloy steels through powder metallurgy (P/M) technique has been under taken in the present research work. The green compacts of 0.5 aspect ratio (h/d) were sintered at 1100 ± 10 °C for 30 min in nitrogen purged electric muffle furnace. The sintered compacts were cold forged to obtain various densities of alloy steels preforms. Electrochemical and aqueous immersion corrosion tests were carried out on the cold forged alloy steels using pickling acid medium at various time periods. The experimental results show that the addition of TiC to the ATOMET 4601 decreases the corrosion rate of alloy steel and the corrosion rate is found to decrease with increase in density in the alloy steel compositions. Surface morphology, SEM, and XRD were also corroborated with the corrosion characteristics of the P/M alloy steels.

Abstract The present paper is aimed to review the efficiency of eco-friendly, natural and cheap bio-waste materials as corrosion inhibitors on metal surfaces in different corrosive media. Various bio-waste materials are the best substitutes for the synthetic organic, inorganic and polymeric inhibitors. Most of the bio-waste material adsorbed on the metal surface in aqueous medium followed the Langmuir adsorption isotherm. The presence of organic constituents in bio-waste materials is responsible for the protection of metals in aggressive medium. The effectiveness of these bio-waste materials to inhibit metal corrosion is well studied by non-electrochemical methods like weight loss and atomic absorption spectroscopy techniques as well as electrochemical methods like polarization and impedance measurements. Surface studies were studied through SEM, EDS, XRD, AFM and XPS techniques. Computational studies using DFT and MDS were also reported.

Abstract The oil and gas industry worldwide is experiencing problems of vandalism and mechanical deterioration due to corrosion in its various pipeline transport systems, a drop in the price of hydrocarbons due to the COVID-19, limitation of maintenance processes. This article provides a contribution original to the knowledge and management of a pipeline transportation system (PTS), without an immediate high impact that would help reduce property loss due to corrosion, through the development of intelligent evaluation models that combine field data, laboratory, and cognitive knowledge in a case study in Mexico. The research is divided into Part 1: modeling, a Fuzzy expert system (FES) unified the knowledge of corrosion specialists and mechanical integrity studies (MIS) and identified evolutionary corrosion patterns with reliability of 0.9029. An artificial neural network (ANN) supported by statistics and metallography establishes test reliability of 0.9556 and determines the corrosion inhibition capacity (C) of Mexican hydrocarbon mixtures based on their properties compared to carbon steel. Part 2: analysis of the operational and economic risk of the PTS under corrosive effects, using Monte Carlo simulation (MCS) estimates various financial scenarios considering corrosive profiles of soils, supply, demand, and inflation.

Abstract The use of magnesium and its alloys as temporary implants has gained interest in the last two decades due to their good mechanical properties and bio-degradability in the in-vivo conditions. However, the issues of higher corrosion rate and stress corrosion cracking persist, which are responsible for the implants’ early failure. This review paper focuses on the challenges involved in the use of magnesium-based implants and the advancements in mitigating the corrosion-related issues for in-vivo use of biodegradable magnesium alloy implants. Herein we review the degradation behavior of three groups of magnesium alloys, i.e., aluminum-containing Mg alloy, rare earth element (REE) containing Mg alloy, and aluminum-free Mg alloy in a variety of testing media. We also review various surface modification techniques such as mechanical methods, physical methods, and chemical methods adopted to address the shortcomings of the Mg alloys. Furthermore, recent developments in Mg based bioimplants such as Mg-based open porous scaffolds, nanostructured Mg alloys and Mg based bulk metallic glasses are reviewed. In the end, recent clinical trials of the Mg-based implant were reported in detail.

We also review various surface modification techniques such as mechanical methods, physical methods, and chemical methods adopted to address the shortcomings of the Mg alloys. Furthermore, recent developments in Mg based bioimplants such as Mg-based open porous scaffolds, nanostructured Mg alloys and Mg based bulk metallic glasses are reviewed. In the end, recent clinical trials of the Mg-based implant were reported in detail.","PeriodicalId":10721,"journal":{"name":"Corrosion Reviews","volume":"40 1","pages":"289 - 333"},"PeriodicalIF":3.2,"publicationDate":"2022-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46698364","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}
