Corrosion and the Environment

The fact that corrosion does occur should not be cause for surprise. Almost all materials should be expected to deteriorate with time when exposed to the elements. Corrosion is a perfectly natural process, as natural as water flowing downhill. If water flowed uphill or remained stationary on a hillside, there may be cause for surprise, yet our human ingenuity can accomplish this by putting water in a closed container (pipe) and closing the bottom end, or merely freezing it. Similarly, if iron or steel were exposed to air and water, rust would be expected to develop within a matter of hours.
