... and corrosion prevention during 2012 will cost approximately $961 billion in the United States alone. Although these numbers may now be somewhat inaccurate, the staggering figures show that corrosion is enormously costly to society. In some cases, corrosion can result in catastrophic failures that lead to loss...
