Available in PDF, EPUB and Kindle. Book excerpt: Atmospheric corrosion behavior was evaluated separately on skyward and groundward surfaces of galvanized steel test panels exposed in both industrial and marine environments. The behavior in every case can be accurately described by the same general kinetic relationship, ?W = KtN, where the empirically determined co-efficients, K and N, can be used to separate the tendency for a corrosion product to form from the effect of that corrosion product on the subsequent reaction. The specific kinetic equations which apply in each case can be used to reliably predict long-term atmospheric corrosion behavior.

Available in PDF, EPUB and Kindle. Book excerpt: A damage function for predicting the corrosion of galvanized steel structures by wet and dry deposition has been developed from the thermodynamics and kinetics of atmospheric corrosion chemistry. The function mathematically expresses the competing reactions for the buildup and dissolution of the basic zinc-carbonate corrosion film with exposure time. Major findings as expressed by the theoretical function are as follows: 1. During periods of surface wetness, SO2 reaching the surface reacts stoichiometrically with the zinc. 2. Rain acidity reacts stoichiometrically with the zinc. 3. The corrosion film of basic zinc carbonate is soluble in clean rain. The dissolution depends on the residence time of rain on the galvanized steel surface. 4. Deposition velocity controls the rate of corrosion of galvanized steel structures by gaseous SO2 during periods of wetness.

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.

Download or read book Corrosion and Electrochemistry of Zinc written by Xiaoge Gregory Zhang and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humankind's use of zinc stretches back to antiquity, and it was a component in some of the earliest known alloy systems. Even though metallic zinc was not "discovered" in Europe until 1746 (by Marggral), zinc ores were used for making brass in biblical times, and an 87% zinc alloy was found in prehistoric ruins in Transylvania. Also, zinc (the metal) was produced in quantity in India as far back as the thirteenth century, well before it was recognized as being a separate element. The uses of zinc are manifold, ranging from galvanizing to die castings to electronics. It is a preferred anode material in high-energy-density batteries (e.g., Ni/Zn, Ag/Zn, ZnJair), so that its electrochemistry, particularly in alkaline media, has been extensively explored. In the passive state, zinc is photoelectrochemically active, with the passive film displaying n-type characteristics. For the same reason that zinc is considered to be an excellent battery anode, it has found extensive use as a sacrificial anode for the protection of ships and pipelines from corrosion. Indeed, aside from zinc's well-known attributes as an alloying element, its widespread use is principally due to its electrochemical properties, which include a well-placed position in the galvanic series for protecting iron and steel in natural aqueous environments and its reversible dissolution behavior in alkaline solutions.

Download or read book Determination of Time of wetness and Corrosion Rates with Atmospheric Corrosion Rate Monitors written by Florian Mansfeld and published by . This book was released on 19?? with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Corrosion damage due to acid deposition has been studied by exposing samples of galvanized steel, nickel and latex house paint (with and without carbonate extender) at three test sites in the Greater Los Angeles area and in Salinas, CA. Atmospheric corrosion rate monitors (ACRM) with zinc or nickel sensors facing the sky or the ground have also been exposed. The ACRMs provide a continuous record of the time-of-wetness and atmospheric corrosion rates. The results of the field tests show that corrosion rates for galvanized steel are very low with the lowest rates being observed in the winter months. The higher corrosion rates observed during the summer are considered to be caused by nitric acid produced by photochemical oxidation of NOx.
