ABSTRACT
Corrosion poses considerable cost and safety threats to infrastructure. Yunovich et al. (2005) observed that the direct annual corrosion costs were about $276 billion as of the time of writing. They also observed that out of that amount, 16.4% is the estimated direct costs of corrosion of infrastructure. That amounts to almost $45.3 billion annually, again in 2005 dollars. They also reported that the indirect corrosion costs are almost 10 times the direct costs. For infrastructure alone, in 2005 dollars, that can amount to nearly half a trillion dollars, annually! Clearly, corrosion is a serious problem than requires serious consideration by all stakeholders.
