Corrosion type, for which the electrolytic metal removal extends only on small surface areas and results in the formation of local cavities (crater-shaped, pinhole-type). Because the amount of the produced corrosion products is only small, pitting is mostly recognized only when leakages occur.
in cast replicas, small holes that are visible through a loop and in time with the naked eye. This can also occur when mounted medals strike each other, or in the case of the Iron Cross as a side effect of rusting.
A localized corrosion process, that can be caused by several factors including cavitation or by high temperature boiling. If pitting is left unchecked by proper corrosion inhibition, part failure will results.
A form of extremely localized attack characterized by holes in the metal. Pitting is one of the most destructive and insidious forms of corrosion. Depending on the environment and the material, a pit may take months, or even years, to become visible.
These are small holes that appear in a dried film, which are usually caused by moisture, grease, or some volatile substance that escapes from the film late in the drying process when the finishing material is unable to flow and fill in the void.
