These 22 contributions concentrate primarily on newer applications of the staple EIS technique, and secondarily, on the more recent use of ENA in corrosion research. Papers treat experimental aspects of EIS and data analysis; EIS for investigating the protective properties and degradation of polymer coatings; and EIS in combination with other techniques to study specific corrosion phenomena, e.g., the corrosive rates of steel in soil environments. Mansfeld (U. of Southern California), et al., describe the use of both techniques to monitor the corrosion behavior of active and passive systems exposed to chloride media. The volume includes facts about the Electrochemical Society. Annotation copyrighted by Book News Inc., Portland, OR.

The new edition of LaQue's classic text on marine corrosion, providing fully updated control engineering practices and applications Extensively updated throughout, the second edition of La Que's Handbook of Marine Corrosion remains the standard single-source reference on the unique nature of seawater as a corrosive environment. Designed to help readers reduce operational and life cycle costs for materials in marine environments, this authoritative resource provides clear guidance on design, materials selection, and implementation of corrosion control engineering practices for materials in atmospheric, immersion, or wetted marine environments. Completely rewritten for the 21st century, this new edition reflects current environmental regulations, best practices, materials, and processes, with special emphasis placed on the engineering, behavior, and practical applications of materials. Divided into three parts, the book first explains the fundamentals of corrosion in marine environments, including atmospheric corrosion, erosion, microbiological corrosion, fatigue, environmental cracking, and cathodic delamination. The second part discusses corrosion control methods and materials selection that can mitigate or eliminate corrosion in different marine environments. The third section provides the reader with specific applications of corrosion engineering to structures, systems, or components that exist in marine environments. This much-needed new edition: Presents a comprehensive and up-to-date account of the science and engineering aspects of marine corrosion Focuses on engineering aspects, descriptive behavior, and practical applications of materials usage in marine environments Addresses the various materials used in marine environments, including metals, polymers, alloys, coatings, and composites Incorporates current regulations, standards, and recommended practices of numerous organizations such as ASTM International, the US Navy, the American Bureau of Shipping, the International Organization for Standardization, and the International Maritime Organization Written in a clear and understandable style, La Que's Handbook of Marine Corrosion, Second Edition is an indispensable resource for engineers and materials scientists in disciplines spanning the naval, maritime, commercial, shipping industries, particularly corrosion engineers, ship designers, naval architects, marine engineers, oceanographers, and other professionals involved with products that operate in marine environments.

Damage from corrosion costs billions of dollars per year. Controlling corrosion requires a fundamental, in-depth understanding of the mechanisms and phenomena involved, and this understanding is best achieved through advanced analytical methods. The first book to treat both surface analytical and electrochemical techniques in a single reference, An

Potential and current noise data have been collected for pure iron foils exposed to 0.5N sodium chloride (NaCl) that was aerated, deaerated, or aerated with sodium nitrite (NaNO2) added as inhibitor. Potential and current noise data were obtained at the beginning of each hour over a 24-h period either sequentially or simultaneously. Statistical and spectral analyses were performed resulting in noise resistance values. For the noise resistance Rn = ?V/?I, where ?V and ?I are the standard deviation values of potential and current, respectively, similar values as for the polarization resistance Rp determined with electrochemical impedance spectroscopy (EIS) at the end of the tests were obtained. The spectral noise resistance Rosn obtained from spectral analysis of simultaneously collected current and potential data agreed satisfactorily with Rp and Rn for aerated and inhibited solutions. Electrochemical noise and impedance data have also been obtained for two polymer coatings on cold-rolled steel during immersion in 0.5N NaCl for five months. The two types of measurements clearly distinguished between the relatively poor performance of the alkyd system and the excellent performance of the epoxy polyamide system. Similar trends with exposure time were observed for the pore resistance Rpo and Rp, on the one hand, and Rn and Rosn on the other hand. However, the numerical values of the parameters obtained with EIS were different from those obtained with electrochemical noise analysis (ENA).
