Practical Self-Study Guide to CORROSION CONTROL

WHY CONTROL CORROSION? Corrosion of metals is a natural process. For the most part, corrosion is quiet, gradual, and unspectacular, unlike other forces of nature such as earthquakes and tornadoes. These natural, dramatic processes we can do very little about except to watch for them, but corrosion can be prevented or at least controlled so that the metals can perform their required tasks. The Cost of Corrosion Reliability and Cost Estimates of the cost of corrosion have been made by several nations (Great Britain, United States, Australia, and others) and all have reached similar conclusions. The direct costs-replacement and costs of corrosion protection-come to roughly 4% of a developed nation's gross national product (GNP) value, which for the United States means about $270 billion annually...
