Abstract:Previous studies have shown that corrosion is very costly and has a major impact on the economies of industrial nations. A 1975 benchmark study by Battelle-NBS pointed out the severe impact on the U.S. economy. The estimates based on the Battelle-NBS study are that the cost of corrosion in the United States alone was approximately $70 billion, which was 4.2 percent of the gross national product (GNP). A limited study in 1995, updating the 1975 figures estimated the total cost of corrosion at approximately $300 billion. However, that study did little more than apply a multiplication factor to the 1975 cost that was equivalent to the GNP growth from 1975 to 1995.
Through discussions between NACE International (The Corrosion Society) representatives, members of Congress, and the Department of Transportation (DOT), an amendment for the cost of corrosion was included in the Transportation Equity Act for the 21st Century (TEA-21), which was passed by the U.S. legislature in 1998. The amendment requested that a study be conducted in conjunction with an interdisciplinary team of experts from the fields of metallurgy, chemistry, economics, and others, as appropriate. Subsequently, the Federal Highway Administration (FHWA) initiated a systematic study to estimate the total metallic corrosion cost and to provide preventive strategies to minimize the impact of corrosion. In the period from 1999 to 2001, CC Technologies Laboratories, Inc. conducted the study in a cooperative agreement with FHWA and NACE International.
