Local corrosion attacks tend to occur because of existing defects when not caused by processing and construction errors. There is a difference between the material’s own intercrystalline corrosion (e.g. metal admixtures, which have a more precious potential than the basic metal); chemical corrosion which is foreign to the material (e.g. oxide layers, casting crust, annealing skin, blacksmith’s residue, mill scale on the material) and corrosion caused by the short-circuiting of metals with different electronegativity in the presence of water (electrolyte).
The DIN standard DIN EN ISO 8044 defines a total of 37 different types of corrosion which are defined based on the location in which they occur:
By the way: corrosion on ferrous material is known as ‘rust’, corrosion on copper and Cu alloys is known as ‘patina’, and on zinc and Zn alloys it is ‘white rust’. And when high temperatures cause oxides to occur, this is known as ‘scale’.
