The global annual cost of corrosion is estimated US$2.5 trillion, which is equivalent to 3.4% of the global GDP (2013)1. Annual cost of corrosion in the United States industries is about US$274 Billion (in 1998) that was 3.5% GDP. Automotive industry sector alone lost US$ 23.4 Billion (in 1998)2. It is estimated that through protective measures against corrosion about 15% - 35% of the cost can be saved. Education plays a major role in reducing the cost of corrosion not only in terms of financial savings, but also in preserving individual safety and environmental protection. In this presentation, authors current research in three segments related to atmospheric corrosion (segment I), corrosion in automotive heat exchangers (segment II), and Flow Accelerated Corrosion (segment III) will be covered.
Atmospheric corrosion of ferrous alloys is typically mitigated through development of protective surface coatings. Research results related to development of super-hydrophobic coatings for protection of low carbon steels is presented. Challenges in automotive and HVAC industries on corrosion of All Aluminum Microchannel Heat Exchangers will also be presented. Furthermore, examples of Flow Accelerated Corrosion (FAC) at elevated temperatures observed in Nuclear and fossil fuel power generating industries will be discussed. Finally, corrosion related research and education opportunities available at UNT within the college of engineering is presented.
