Answer:

When metals are exposed in the presence of water, whether fresh, brackish or salt, marine corrosion is inevitable. From the moment they are manufactured, nearly all metals are trying to return to the original form in which they existed when we dug them out of the ground.

The three types of corrosion boaters typically work to manage are:

Simple electrochemical corrosion

Galvanic corrosion

Electrolytic/stray current corrosion

All three types of marine corrosion are the result of an electrochemical process, the difference is how fast the corrosion occurs. The process speeds up when multiple metals are involved (galvanic corrosion) and faster still when unwanted electrical currents are applied (stray current corrosion). While the result of any of these types of corrosion is pretty much the same – exposed metal damage – there can be many reasons why the corrosion occurred in the first place. The challenge we face is identifying the type of corrosion and finding its true cause to minimize future corrosion.

Answer:

Probably the most important factor in corrosion of steels in coal mines is the mine water; however, just as with other industrial waters, the composition and corrosivity of these waters are highly variable. Yet little has been done by the mining industry to develop a comprehensive understanding of mine water corrosion, let alone allow effective modeling of corrosion caused by water. Rawat1 concluded that corrosion in coal mines was attributable to high relative humidity (>90%), high temperature (~30 °C [86 °F]), and airborne dusts
