A May 2001 symposium in Phoenix, Arizona was originally intended to present results of the Society's 1976 international outdoor atmospheric corrosion test program; it was soon combined with another being planned on indoor corrosion, but the indoorists stayed home, so all of the 29 papers consider ou

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.

Atmospheric corrosion may cause serious damage to metallic structures and equipments. Because of the huge impact of corrosion, it is imperative to have a systematic approach to recognizing and justifying corrosion problems as soon as possible after they become apparent. In this study, the impact of atmospheric corrosion on aluminum, copper and zinc was investigated by exposing the sample in indoor and outdoor atmosphere. Each sample undergoes environmental exposure for 28 days before the surface morphology investigation was conducted. Then the cleaning process follows prior to the final analysis. Scanning Electron Microscope (SEM) was used to study the surface morphology. Corrosion rate was determined for all samples. In indoor environment, it was found that zinc possess the highest corrosion rate; 1.440 mpy while aluminum is the less corrosive sample with only 0.2645 mpy. The outdoor environment investigation yield similar polar of result where the value increase in almost double the result from indoor investigation. Corrosion rate of zinc is 2.103 mpy and the less corrosive sample; aluminum is 0.417 mpy. Any features of corrosion failure give significant clue of the possible corrosion factor. This article details a proven approach to properly determining the effects of the environment and material types to the corrosion rate, and includes surface microstructure of the most common corrosion types, including general corrosion, pitting, and erosion. In conclusion, properties of outdoor and indoor influence the corrosion rate. Indoor environment shield the samples from rain and dew hence decrease the corrosion rate compare to open or outdoor environment where the samples subjected to the dynamicity of weather. Aluminum proves to be the most protective sample and corrosion durable. Hence it may suggest that for both indoor and outdoor application, aluminum is highly recommended.

Simulation tests for indoor and outdoor atmospheric corrosion appear essential to reliably predict the behavior of designs and materials in operating environments. Chamber tests are preferentially conducted for indoor corrosion. Some results are given concerning the sulfidation of copper and silver by H2S (hydrogen sulfide) in the presence of additives such as NO2 (nitrogen dioxide) or Cl2 (chlorine molecule). It is shown that chemical reactions between gases are responsible for the acceleration of the rate of sulfidation of metals. Comparison with onsite measurements shows that several classes of test severities must be defined. In studying outdoor atmospheric corrosion, attention is presently focused on the use of electrochemical sensors, which allow the determination of times of wetness and corrosion rates. Chamber tests may be used in some special cases. An example is given for the behavior of metallic materials exposed to corrosion under storage conditions. The combination of chamber and electrochemical tests has led to some understanding of the mechanism of formation and spread of corrosion products for an Fe-Ni alloy. The alloy has a behavior intermediate between that of an active (iron-like) material and a self-passivated (stainless steel-like) one, depending on the aeration conditions of the surface.
