Bronze disease is an irreversible and nearly inexorable corrosion process that occurs when chlorides come into contact with bronze or other copper-bearing alloys. [1] It can occur as both a dark green coating, or as a much lighter whitish fuzzy or furry green coating. [ 1 ]
Protective elements for bronze fountains are particularly important, since water is one of the leading causes for alterations or corrosion in a bronze. [2] Bronze sculptures incorporated in fountains will need more layers of wax, because the spray of water will cause deterioration of the wax at a faster pace than would normally happen.
The most common liquid metal to cause embrittlement is mercury, as it is a common contaminant in the processing of hydrocarbons in petroleum reservoirs. [19] The embrittling effects of mercury were first recognized by Pliny the Elder circa 78 AD. [20] Mercury spills present an especially significant danger for airplanes.
Erosion corrosion, also known as impingement damage, is the combined effect of corrosion and erosion caused by rapid flowing turbulent water.It is probably the second most common cause of copper tube failures behind Type 1 pitting which is also known as Cold Water Pitting of Copper Tube.
Concentration cells can form in the deposits of corrosion products, leading to localized corrosion. Accelerated low-water corrosion (ALWC) is a particularly aggressive form of MIC that affects steel piles in seawater near the low water tide mark. It is characterized by an orange sludge, which smells of hydrogen sulfide when treated with acid.

"A single vehicle has the potential to cause a large mass casualty incident that overwhelms local and mutual aid resources," he wrote in his analysis. "Additionally, the traumatic injuries that ...
Tarnish does not always result from the sole effects of oxygen in the air. For example, silver needs hydrogen sulfide to tarnish, although it may tarnish with oxygen over time. It often appears as a dull, gray or black film or coating over metal. Tarnish is a surface phenomenon that is self-limiting, unlike rust. Only the top few layers of the ...
