Forms of Corrosion

G eneral, or uniform, corrosion is usually the least threatening type of attack because associated metal loss is distributed over a wide surface area. This allows predicting the probable life of equipment with some degree of accuracy.

What is uniform corrosion? Uniform corrosion or general corrosion, as sometimes called, is defined as a type of corrosion attack deterioration that is more or less uniformly distributed over the entire exposed surface of a metal see illustration below. Uniform corrosion also refers to the corrosion that proceeds at approximately the same rate over the exposed metal surface. Cast irons and steels corrode uniformly when exposed to open atmospheres, soils and natural waters, leading to the rusty appearance. The photo on the right showed uniform corrosion rusting of a pair of steel nuts used to fasten a galvanized steel clamp on a street lamp post.

Uniform Corrosion

Case histories and illustrations of specific forms of corrosion. This book presents detailed case histories and illustrations of specific forms of corrosion. Each chapter, written by an expert, begins with an illustrated introduction explaining the specific form of corrosion and its prevention, followed by illustrated case histories of the phenomenon. It contains information on general, localized, and galvanic corrosion; environmental cracking, erosion-corrosion, cavitation, and fretting; intergranular corrosion; dealloying; and high-temperature corrosion performance. Chemical corrosion inhibitors. Conversion Tables.

Forms of Corrosion

In a previous post, we discussed the basics of corrosion -- from the fundamental chemical reaction to the types of environments in which corrosion can occur. As corrosion most often occurs in aqueous environments, we now explore the different types of degradation a metal can experience in such conditions:. Uniform corrosion is considered an even attack across the surface of a material and is the most common type of corrosion. It is also the most benign as the extent of the attack is relatively easily judged, and the resulting impact on material performance is fairly easily evaluated due to an ability to consistently reproduce and test the phenomenon. Pitting is one of the most destructive types of corrosion, as it can be hard to predict, detect and characterize.
