Steel is among the most important implements in construction work. Most structures and equipment would not at all be viable without it. However, this material is also very much vulnerable to an insidious problem, corrosion. One particular type of it that is particularly dreaded is rust pitting.
This kind of corrosion is typified by a localized perforation or holes in the metal. It is galvanized by the actuality in which a small anodic area is surrounded by a large cathode one. That forms a rusty sheen that penetrates the metal its whole mass through, sapping essential ions along the way.
In certain environments, the effects of rust are even more considerable. For example, there is the coastal region. This is because of the high degrees of humidity and the constant spewing of sea spray. Bare metal can then quickly accrue damage.
Even corrosion products, with its beneficent purposes, can be adverse to the whole thing. That is because it covers or obscures the pits. Therefore, these crevices can be really hard to spot, and may only be noticed after extreme, irreversible damages.
All implements, structures, and supporting frameworks have been carefully engineered prior to their installation. Therefore, the loss of mass and thickness can result to significant problems. The metal fatigue caused by the loss of beam mass and some such will go on to a gradual degeneration that may result to a catastrophic breakdown later.
The thing with pitting is that it is not merely the formation of coppery sheen. It also involves the loss of material. Since the metal is gone, its place is amenable to hiding moisture and small rust particles, that which holds continued detriment to the remaining integral structure. Consequently, you cannot just go on an paint anti oxidation coatings over it.
Bridges are also susceptible to this kind of gradual damage. This is also as dangerous, especially since the damage occurs under the surface and therefore is not altogether noticeable. One will perhaps only notice it after the disastrous breakdown or snapping of the said structure due to stress corrosion cracking. Really, though, the best course of action is to use quality metal and protective coating right off the bat. Also, it is nifty to examine perforations, no matter how little and negligible they may seem.
Other implements that can suffer from pitting are firearms. It especially forms in the barrel part. The damages to the bore will riddle the firearm with deformities. Consequently, the weapons accuracy will be greatly reduced, and that may perhaps cause safety concerns and some such. A chromium lining does great in preventing pit formation in bores.
Pit corrosion is an insidious adversary. It is difficult to detect and design against. It may also be unpredictable and come in many different configurations. Its dangerous because even a small pit can gradually cause maximal metal loss and result in fatigue of a whole, comprehensive system. Therefore, certain care should be employed in preventing it, and prudence must be exercised in deciding the right kind of treatment for it.
