Everyday, corrosion silently gnaws at materials and machines exposed to the elements. Not so quietly, however, it gnaws at the pocket- book of the economy. This year alone, corrosion will cost the United States about $150 billion. "It's everywhere you look," says Money of The LaQue Center for Corrosion Technology, Inc., at Wrightsville Beach. Our cars, bridges, screen doors and even our hammers are affected by it. It's the job of the center to research the forces of corrosion and help find some solutions. Money says corrosion occurs because "when we form, or make, or shape materials into alloys . . we've altered the natural -•state of that material into some form that we can use. In just the laws of nature, those materials have a tendency to want to return to their natural state. Steel wants to return to iron ore, and as a result, it will have a tendency to corrode. The same thing's true with aluminum, copper-based alloy and any of the other alloy ; Corrosion is often confused with rust, but there's really no difference between the two, Money says. Rust is the corrosive mechanism of iron-based materials such as iron and steel. The coastal environment, although not the worst, is highly susceptible to corrosion. "The materials used in and around the marine environment, in sea water and coastal zone areas, are seriously affected, of course, by the strong, corrosive sodium chloride, which is the main constituent of sea water,"
