A cavity in a metal surface resulting from localized corrosion and eventually leading to leaks in the system.
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.
The presence of pin holes or small craters in the solder joint caused by oxidation, plating material or other foreign incompatible matter. Such joints are generally also dull in finish.
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.
Localised surface defects on metals, in the form of small depressions, or "pits"
Highly localized corrosion resulting in deep penetration at only a few spots.
A concentrated attack by oxygen or other corrosive chemicals in a boiler, producing a localized depression in the metal surface.
Small cavities in a metal surface by nonuniform electrodeposition or by corrosion.
Small holes in the surface of a coin or die, often caused by a damaged die or even blank.
Making shallow pits and/or basins to reduce overland flow. (Also used for seedbed.)
the formation of small pits in a surface as a consequence of corrosion
A natural occurring pit or divot on the surface of a gemstone.
A condition in which the film is marked by fine holes which do not go through to the substrate.
Small holes that form in a floor finish or hard surface. A common cause of this are "spiked" heel shoes worn by women in the workplace.
Surface cavities; may be related to fatigue, overload or corrosion.
Formation of small, usually shallow depressions, cavities, or holes in a dried film.
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.
Localized corrosion of a metal surface, confined to a point or small area, that takes the form of cavities or pits.
The development of small cavities in masonry surface caused by natural weathering erosion of harsh cleaning methods. Occurs in concrete due to improper mixing.
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.
Localized corrosion (in the form of pits) of a metal surface that is confined to a small area.
Holes or other irregularities caused by corrosion on metallic surfaces.
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.
Localized corrosion on a metal surface.
coating defect consisting of randomly spaced small depressions in the cured film. Pitting is similar to pinholing, except that pits do not expose the bare substrate.
1. Defect that occurs when paint has tiny bubbles that break as the paint dries. 2. Spotted metal corrosion. 3. Drywall defect of small pits in the joint compound after drying.
A form of wear characterized by the presence of surface cavities, the formation of which is attributed to processes such as fatigue, local adhesion, cavitation or corrosion.
