 “Corrosion Resistant Materials for Extreme Environments”

ABSTRACT:

Materials of all classes, including metals, glass, and crystalline ceramics, are created at the expense of energy. However, these materials are often exposed to hostile environments and are subjected to corrosion, which is a thermodynamically favorable process. Corrosion not only comes with substantial economic costs, but also leads to unpredictable safety issues. This is of particular concern for structural materials exposed to extreme service environments, such as high temperature, high pressure, extremely acidic/oxidizing, and radioactive conditions. Therefore, it is of paramount importance to develop effective strategies to combat corrosion in these environments. This talk will center on applying laser powder bed fusion, an additive manufacturing technique, to create alloys with exceptional mechanical and corrosion properties. A self-accelerated corrosion phenomenon occurring at the interface of different classes of corrosion resistant materials will also be discussed. These studies have direct implications for the design and manufacture of highly corrosion resistant materials that can withstand extreme environments.

BIOGRAPHY:

Dr. Xiaolei Guo is a research associate in the Department of Materials Science and Engineering at The Ohio State University. He also serves as the deputy director of the Center for Performance and Design of Nuclear Waste Forms and Containers (WastePD), a large, interdisciplinary Engineering Frontier Research Center funded by the Department of Energy. Dr. Guo earned his bachelor’s degree in Polymer Science and Engineering from Zhejiang University (China) in 2010 and his Ph.D. degree in Materials Science and Engineering from The Ohio State University in 2016. His research interests include additive manufacturing, localized corrosion of alloys, corrosion interaction between different nuclear waste materials, smart coatings for corrosion mediation, and machine learning assisted materials design. He is the author of 37 research articles, including publications in Chemical Reviews and Nature Materials. He is an instructor of the Ohio State University Corrosion Short Course. He also serves as a topic editor of Coatings journal.
