General, Uniform Corrosion

Corrosion is an on-going attack found in both metals and materials. Uniform, general corrosion is the form we encounter most frequently. It occurs in vehicles, infrastructure, pipelines, and in most things we come into contact with. Coatings, metallurgical alloy improvements, and good maintenance practices are common ways to minimize general corrosion.

The metal loss is uniform in nature, and readily apparent. Often general corrosion problems can be solved by a adding corrosion allowance;. The designer can increase the material thickness in a bridge, tank or pipe line so its life expectancy is reached before there is an unacceptable loss of metal.

Metals that are susceptible to general corrosion are steels, and aluminum and copper based alloys.
