The effects on atmospheric corrosivity of carriage of sea-salt inland from ocean coasts have been largely neglected by researchers except for regions within a few kilometers from the sea. In island nations, salt-affected zones can cover large percentages of total land area. The extent of carriage of sea-salt inland, and correlation to this of the corrosion rates of metals, is assessed in two areas of New Zealand. A sheltered surface collector is erected at each of 18 sites at up to 90 km inland. The site had been chosen to minimize the likelihood of industrial pollution. Each collection rack had attached to its top a test unit with an aluminum wire on a threaded stud (Climat test unit) and a rod holding a pair of steel coupons. There was very good correlation of the steel corrosion rate (48 weeks of exposure) to the log (chloride deposition), and to the 48-week average steel stud value in the 12-week Climat test. The Climat test, because of its ease of performance, thus seems to be a cost-effective means of assessing likely corrosion problems in purely marine environments. The results suggest that sea-salt mediated corrosion rates at distances 20 km and more inland are higher than might have been expected from published reports of studies on continental land masses.

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.

Contains papers presented at a November 2000 symposium, examining laboratory evaluation methods, test methods, and model prediction in research on atmospheric corrosion, corrosion of rebar in concrete, marine corrosion, and other related corrosion phenomena. Topics include degradation of fiber reinf

This book serves as a reference for engineers, scientists, and students concerned with the use of materials in applications where reliability and resistance to corrosion are important. It updates the coverage of its predecessor, including coverage of: corrosion rates of steel in major river systems and atmospheric corrosion rates, the corrosion behavior of materials such as weathering steels and newer stainless alloys, and the corrosion behavior and engineering approaches to corrosion control for nonmetallic materials. New chapters include: high-temperature oxidation of metals and alloys, nanomaterials, and dental materials, anodic protection. Also featured are chapters dealing with standards for corrosion testing, microbiological corrosion, and electrochemical noise.

Corrosion of Aluminium, Second Edition, highlights the practical and general aspects of the corrosion of aluminium alloys. Chapters help readers new to the topic understand the metallurgical, chemical and physical features of aluminium alloys. Author Christian Vargel adopts a practitioner styled approach that is based on the expertise he has gained during a 40-year career in aluminium corrosion. The book assesses the corrosion resistance of aluminium, a key metric recognized as one of the main conditions for the development of many uses of aluminium in transport, construction, power transmission, and more. Features 600 bibliographic references, providing a comprehensive guide to over 100 years of related study Includes numerous illustrations to enhance study Presents practical applications across many industries Provides an accessible reference for both beginners and experts
