Download or read book Electrochemical Atomic Force Microscopy and Spectroscopic Characterization of Amphiphilic Surfactant Molecules as Corrosion Inhibitors written by Huiru Wang and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective management of pipeline steel corrosion is crucial for asset integrity, CAPEX/OPEX optimization, employee safety and environmental protection for the oil and gas industry. Organic inhibitors, especially of amphiphilic surfactant types, can efficiently reduce corrosion rates when added in small amounts to pipeline transmission systems. Electrochemical methods such as linear polarization resistance, electrochemical impedance spectra, and polarization curves have been adopted extensively to investigate corrosion reaction processes under inhibition, with surface analysis techniques usually playing insignificant roles and only providing elementary information without deeper analyses relating to inhibitor adsorption studies. However, the function of amphiphilic inhibitors depends on their adsorption on the metal surface. Traditional electrochemical measurements cannot usually provide direct information regarding inhibitor adsorption behavior. Therefore, a crucial knowledge gap exists in the fundamental understanding of inhibitor adsorption modes and corrosion inhibition mechanisms, due to the limited application of surface analysis techniques in corrosion inhibitor studies. Given its high resolution, a powerful surface characterization tool with multiple operation modes and good performance in aqueous solution, atomic force microscopy (AFM) has been widely used in surfactant studies for various inert substrates such asmica, graphite, and the noble metal gold. However, AFM has not often been used in with corrosion inhibitor studies involving mild steels. In the few studies AFM was used only to do straightforward surface roughness comparisons and provide some supplementary corrosion morphology evidence. In contrast to these previously reported inhibitor studies, the research reported in this dissertation will show how AFM can be used much more effectively as a main technique for improving the mechanistic understanding of the inhibition behavior of amphiphilic inhibitors adsorbed on a mild steel surface. Multiple AFM operation modes and imaging techniques were developed to systematically investigate the adsorption mechanism and corrosion inhibition mechanism of a quaternary ammonium inhibitor on a UNS G1018 steel. Finally, another two advanced high resolution surface chemistry analysis techniques, Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) and X-ray Photoelectron Spectroscopy (XPS) were adopted to identify inhibitor adsorption properties as well as electrochemical reaction mechanisms, and compared with AFM findings. The findings in the present study indicate a relationship between adsorption morphology and inhibitor concentrations, as well as verified the existence of surface saturation concentration (SSC) found in electrochemical tests. The AFM findings suggest that adsorbed inhibitor molecules formed a continuous film with multiple defect areas when added above the SSC. This can provide an answer for the long standing research question as to why the inhibition efficiency does not reach 100% even when inhibitor concentration is higher than SSC, and is important in terms of developing corrosion prediction models. Meanwhile, the present work found the inhibitor adsorptionmorphology evolves from discontinuous aggregates, then non-uniform film with large defects, finally to a uniform film with defects when the bulk inhibitor concentration varies from low to high. The corresponding corrosion morphology evolves from uniform corrosion at a high rate, patchy corrosion, and full protection respectively, as demonstrated by electrochemical atomic force microscopy (EC-AFM). This AFM finding can be used to connect the inhibitor adsorption isotherm (surface coverage versus inhibitor concentration) with the actual surface corrosion processes, and builds a bridge between adsorption and corrosion studies. Furthermore, the present AFM work suggests that the mild steel microstructures could influence inhibitor adsorption, specifically how inhibitor is adsorbed on cementite structure that could be more easily removed by flow, than on ferrite structures. This is significant as inhibition efficiency often decreases as the carbon content of the steel increases. Finally, the ToF-SIMS and XPS work verified the relationship between adsorption, corrosion and inhibitor concentration elucidated by AFM, and further determined the inhibitor adsorption types and surface layer structures based on the composition analysis from top surface to steel substrate depth. By these findings, a fundamental understanding of the relationship between inhibitor chemical structure, molecular orientations during adsorption, and corrosion inhibition efficiency at various inhibitor concentrations and immersion times has been built, which ca be of great significance for choosing proper inhibitors for specific environments or even design of new inhibitors. Moreover, a surface analysis methodology for studying the interface between amphiphilic inhibitors and mild steel is developed on the basis of the AFM technique. This AFM methodology has beencombined with surface chemistry analysis, molecular simulation, and electrochemistry to provide comprehensive information regarding corrosion inhibition mechanisms

Available in PDF, EPUB and Kindle. Book excerpt: ATMOSPHERIC CORROSION Presents a comprehensive look at atmospheric corrosion, combining expertise in corrosion science and atmospheric chemistry Atmospheric corrosion has been a subject of engineering study, largely empirical, for nearly a century. Scientists came to the field rather later on and had considerable difficulty bringing their arsenal of tools to bear on the problem. Atmospheric corrosion was traditionally studied by specialists in corrosion having little knowledge of atmospheric chemistry, history, or prospects. Atmospheric Corrosion provides a combined approach bringing together experimental corrosion and atmospheric chemistry. The second edition expands on this approach by including environmental aspects of corrosion, atmospheric corrosion modeling, and international corrosion exposure programs. The combination of specialties provides a more comprehensive coverage of the topic. These scientific insights into the corrosion process and its amelioration are the focus of this book. Key topics include the following: Basic principles of atmospheric corrosion chemistry Corrosion mechanisms in controlled and uncontrolled environments Degradation of materials in architectural, transport, and structural applications; electronic devices; and cultural artifacts Protection of existing materials and choosing new ones that resist corrosion Prediction of how and where atmospheric corrosion may evolve in the future Complete with appendices discussing experimental techniques, computer models, and the degradation of specific metals, Atmospheric Corrosion, Second Edition continues to be an invaluable resource for corrosion scientists, corrosion engineers, conservators, environmental scientists, and anyone interested in the theory and application of this evolving field.

Available in PDF, EPUB and Kindle. Book excerpt: All significant studies agree that aqueous corrosion continues to cost nations dearly in almost every area of technological endeavour. Over the past ten years, microcomputers have facilitated an explosion in the power of modelling as a technique in science and engineering. In corrosion they have enabled better understanding of polarization curves, they have transformed the scope of electrochemical impedance measurements and they have placed a large range of electrochemistry at the fingertips of the corrosion scientist. This book focuses on the models, rather than the computing, which have been made possible during the past decade. Aimed at all those with an interest in corrosion and its control, the book draws together the range of new modelling strands, suggests new avenues of approach and generates further momentum for improvements to corrosion management, whether by increased understanding of atomistic processes or by control of large plant.
