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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Frequent phase identifications of a large number of zinc panels exposed to different atmospheric conditions, both in national an international exposure programs, have revealed a variety of corrosion products. In order to extract basic information about the atmospheric corrosion processes involved, emphasis has been placed on more precise characterization of corrosion products, from the initial stages to full developed end products. Extensive field exposures under rain sheltered conditions have been performed in rural, urban, industrial and marine atmospheres. These programs have included different methods for surface and bulk analysis of corrosion products, as well as measurements of deposition rates for gases and aerosols, and measurements of climatic parameters. Depending on atmospheric conditions, the complex growth of corrosion products seems to result in end products containing at least one of the structurally related phases: Zn5(CO3) 2(OH)6, Zn5(OH)8Cl2 •H2O, Zn4SO4(OH)6 • 4H2O, Zn4Cl2(OH)4SO4 • 5H2O and NaZn4Cl(OH)6SO4•6H2O.

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: The Bureau of Mines, U.S. Department of the Interior, as part of the National Acid Precipitation Assessment Program, is conducting a field exposure program to measure the corrosion damage on commonly used structural metals and the incremental effects of acidic deposition and other environmental variables. Corrosion damage, air quality, rain chemistry, and meteorology are being continuously measured at five sites in the Eastern and Midwest United States for periods up to 84 months. Corrosion damage on zinc for periods up to 36 months was determined from weight-loss measurements, analysis of corrosion film chemistry, and of precipitation runoff chemistry. The results suggest the long-term zinc corrosion film consists of a stable inner layer sensitive to atmospheric sulfur dioxide (SO2) concentrations and a nonprotective outer layer. A synergistic reaction involving SO2 and nitrogen dioxide (NO2) may occur. Dry deposition of SO2 and NOx on the corrosion film is substantial. Zinc losses from the corrosion film are proportional to hydrogen ion loading. Covariance between many air quality and rain chemistry variables may be low enough to avoid, to a considerable degree, problems in developing linear regression models of corrosion damage.

Available in PDF, EPUB and Kindle. Book excerpt: Zinc (Zn) coatings on steel structures for corrosion protection are by far the greatest use of Zn throughout the world. Numerous experiments have been conducted in laboratory environments to predict and understand the corrosion behavior of Zn coatings in the field. However, many studies have been limited to time of wetness, pH, and chloride (Cl-) and sulfur dioxide (SO2) concentrations to predict the Zn corrosion rate. The corrosion behavior of Zn exposed to 120 ppb SO2, 550 ppb ammonia (NH3), 650 ppb ozone (O3), and ultraviolet (UV) light at 70% RH, with a constant preloading of sodium chloride (NaCl) was investigated in this study. After exposure, corrosion rates were measured using mass loss and corrosion products were identified by x-ray diffraction (XRD), fourier transform infrared spectroscopy (FTIR), and energy dispersive spectroscopy (EDS). UV light and O3 did not significantly affect the Zn corrosion rate in the absence of Cl-. However, when NaCl was present, UV light inhibited the Zn corrosion rate below 90% RH and accelerated the Zn corrosion rate at 99% RH. The presence of UV light also increased the formation of zinc hydroxy sulfate and gordaite when exposed to 120 ppb SO2 and NaCl. The combination of SO2 and O3 with the preloading of NaCl increased the corrosion rate of Zn compared to NaCl alone. 550 ppb NH3 was determined not to have a significant effect on the Zn corrosion rate.

Book excerpt: The corrosion of zinc in the atmosphere is controlled by three principal factors: (1) the frequency of rain and dewfall, (2) the acidity of the moisture, and (3) the rate of drying. The corrosion rate is a maximum in industrial locations which combine acidic atmospheric contamination with prevalence of heavy mists and dew. The composition of zinc has only a minor bearing on the corrosion rate. Corollary data are presented which explain the findings in exposure tests conducted by Subcommittee VI on Atmospheric Corrosion of Committee B-3 on Corrosion of Non-Ferrous Metals and Alloys.
