Left unprotected, metals corrode quickly which over time contributes to the loss of structural integrity and the failure of buildings, bridges, oil & gas platforms, airplanes, cars and many other metal assets, all of which pose a risk to human safety and the surrounding environment. In 2016, the National Association for Corrosion Engineers (NACE) – now known as AMPP – published a landmark study, well-known to those attending this conference, that estimated the direct cost of corrosion to the world economy as $2.5T per year, equivalent to 3.4% of the Gross World Product (1). In the United States, the annual cost of corrosion is estimated at 3.1% of gross domestic product (2), equivalent to $635B (2018). When including indirect costs, such as asset downtime, ship dry-docking and the impact of bridge collapses, the cost of corrosion is estimated at twice that amount.
