No metal is immune from some reduction of its resistance to cyclic stressing if the metal is in a corrosive environment. The rapid corrosion that occurs at the interface between contacting, highly loaded metal surfaces when subjected to slight vibratory motions is known as fretting corrosion. Erosion Corrosion Erosion corrosion is the result of a combination of an aggressive chemical environment and high fluid-surface velocities. Dealloying Dealloying is a rare form of corrosion found in copper alloys, gray cast iron, and some other alloys. Hydrogen Damage Hydrogen embrittlement is a problem with high-strength steels, titanium, and some other metals.
Control is by eliminating hydrogen from the environment or by the use of resistant alloys.
The steel is necessary to maintain the strength of the structure, but it is subject to corrosion. This corrosion can take many forms and can be controlled by biocides or by conventional corrosion control methods. August 24, 2000.
