Corrosion, as partial or total disintegration of a material due to chemical reaction with its surroundings, is the process that, next to wear, determines the lifetime of a part. Whether this lifetime is defined by how long reliable functionality is given or just by how long a desired cosmetic aspect can be maintained, the information on the corrosion behavior is crucial for the use in technical applications. The fundamental chemical reactions leading to corrosion in general and to the oxidation of metal specifically are given in Fig. 1.
