Corrosion

Definition of corrosion: the chemical or electrochemical reaction between a material, usually a metal, and its environment that produces a deterioration of the material and its properties.

See also corrosion fatigue, crevice corrosion, denickelification, dezincification, erosion corrosion, exfoliation, filiform corrosion, fretting corrosion, galvanic corrosion, generai corrosion, graphitic corrosion, impingement attack, interdendritic corrosion, intergranular corrosion, internal oxidation, oxidation, parting, pitting, poultice corrosion, rust, selective leaching, stray-current corrosion, stress-corrosion cracking, and sulfide stress cracking.

Definition of corrosion fatigue: cracking produced by the combined action of repeated or fluctuating stress and a corrosive environment at lower stress levels or fewer cycles than would be required in the absence of a corrosive environment.

There are many types of corrosion and there are many different causes with different names.
Erosion is a strictly mechanical form of corrosion that is caused by friction. There is another type of erosion, which is caused by high speed water flow.

To protect components from corrosion there are many products and techniques. The galvanizing, is one of the most used corrosion protection system for metals. This process must be made with high attention for the metallurgic aspects.
