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. The book concerns primarily the atmospheric corrosion of metals and is written at a level suitable for advanced undergraduates or beginning graduate students in any of the physical or engineering sciences.

Book excerpt: This book aims to provide comprehensive and systematic introduction and summary of corrosion characteristics, mechanisms, and control methods of candidate alloys in sub- and supercritical water environment. First of all, corrosion types of candidate alloys and the effects of major alloying elements on corrosion resistance of potential alloys in sub- and supercritical water are compared and analyzed. At the same time, research status of candidate materials, and development and application trends of several corrosion-resistant alloys are summarized. Then, corrosion characteristics of Ni-Cr, Ni-Cr-Mo, Ni-Fe-Cr and Ni-Fe-Cr-Mo-Cu corrosion-resistant alloys, FeCrAl alloy, and Zircaloy are discussed in detail, including the corrosion rate, the structure and composition of oxide film, and the effects of various surface treatment processes, etc. More specifically, it also investigates corrosion behavior of Ni-based alloy, Fe-Ni-based, and stainless steels in supercritical water. The effects of aggressive species on the corrosion behavior of Ni-base alloys are also explored in supercritical water. Readers will further discover the total corrosion processes and mechanisms of typical candidate alloys in sub- and supercritical water environment. Finally, the work explores the corrosion control methods such as ceramic coatings and passivation processes in supercritical water oxidation and in subcritical water, respectively.

It offers valuable reference for theoretically guiding material selection and design and operating parameter optimization of key equipment in the sub- and supercritical water technologies. The book is written for senior undergraduates, graduate students, scholars, and researchers who are interested in corrosion behavior of candidate materials of supercritical water oxidation system, supercritical water gasification system, and nuclear reactor.
Download or read book The Influence of Alloying Elements on the Crevice Corrosion Behaviour of NI CR MO Alloys written by Nafiseh Ebrahimi and published by . This book was released on 2015 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: To enhance its corrosion resistance in aggressive media, Ni is alloyed with various amounts of Cr and Mo along with small amounts of other alloying elements such as W, Cu, and Fe. While the resulting alloys (known as Ni superalloys) show excellent passive behaviour, the function of individual alloying elements in resisting localized corrosion processes, in particular crevice corrosion is not fully understood. This study focuses on the electrochemistry and corrosion of a series of Ni-Cr-Mo (W) alloys with various Cr and Mo contents. Several electrochemical and surface characterization techniques were used to investigate the role of major alloying elements on maintaining passivity and protecting the alloy under crevice corrosion conditions. To initiate crevice corrosion, either galvanostatic or galvanodynamic polarization was used. Using these techniques to apply an electrochemical current the cathodic reaction on the counter electrode is controlled simulating the cathodic reaction needed to drive the anodic crevice corrosion reaction. A comparison of the crevice corrosion behaviour, controlled galvanostatically, of C22 (Ni-22Cr-13Mo-3W), BC1 (Ni-16Cr-22Mo) and C625 (Ni-21Cr- 9Mo) in 5 M NaCl solution at 150°C shows that crevice initiation is mainly controlled by the Cr content of the alloy while both Cr and Mo (Mo +W) synergistically determine the crevice activation rate. Once the crevice is activated, the corrosion damage propagation profile is dominantly influenced by the Mo (Mo + W) content of the alloy and also by the applied current. Higher currents and a higher Mo + W content lead to shallower and more laterally distributed corrosion damage. A series of weight change measurements on BC1, galvanostatically crevice corroded to a constant applied charge, show that internal proton reduction plays a key role in supporting active alloy dissolution, with more than 50% of the corrosion damage supported by this reaction. The results indicate that the alloy resists initiation of crevice corrosion, but once initiation has occurred it can continue to propagate spontaneously. The properties of the oxide films anodically formed on the alloys were investigated before and after a period of dissolution at pH 7 and 9 using electrochemical impedance spectroscopy (EIS), X-ray photoelectron spectroscopy (XPS) and Auger electron spectroscopy (AES). The purpose of these experiments was to determine the properties of the passive film formed on the alloy after transpassive dissolution. While Cr is the main element in maintaining passivity, the corrosion resistance of the reformed passive film after transpassive break down is enhanced mainly by Mo. Investigation of the crevice corrosion damage morphology beneath corrosion products, showed intergranular corrosion initiated preferentially on high energy random grain boundaries. Transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS) analyses of grain boundaries showed needle shaped inclusions enriched in oxygen and depleted in nickel were present on these boundaries but not on the dominant 3 boundaries.

Download or read book The Influence of Marine Microfouling on the Corrosion Behaviour of Passive Materials and Copper Alloys written by and published by . This book was released on 2008 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of marine biofilms on corrosion varies with alloy composition. At temperatures below 60 C, resistance to crevice corrosion is the limiting factor for selecting alloys for seawater service and is the most problematic issue affecting the performance of passive alloys in seawater. Several investigators have documented the tendency for biofilms to cause a noble shift, or an ennoblement, in open-circuit potential (OCP) of passive alloys exposed in marine environments. Ennoblement in marine waters has been ascribed to depolarization of the oxygen reduction reaction due to organometallic catalysis, acidification of the electrode surface, the combined effects of elevated H2O2 and decreased pH and the production of passivating siderophores. The alloys tested include, but are not limited to: UNS S30400, S30403, S31600, S31603, S31703, S31803, N08904, N08367, S44660, S20910, S44735, N10276, N06625, platinum, gold, palladium, chromium, titanium, and nickel. Theoretically, potential ennoblement should increase the probability for pitting and crevice corrosion initiation and propagation, especially for alloys with pitting potentials within 300 mV of the OCP. The relationship between passive alloy composition and ennoblement will be discussed. The well-known toxicity of cuprous ions toward living organisms does not mean that the copper-based alloys are immune to microbial colonization and microbiologically influenced corrosion (MIC). It does mean, however, that only those organisms with a high tolerance for copper are likely to have a substantial effect. Most of the reported cases of MIC of copper alloys in marine environments are not related to ennoblement of OCP, but are caused by the reduction of sulfate (concentration> 2 gm/L) to hydrogen sulfide.
