Rhines Hall 125



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 incurs substantial economic costs but also poses unpredictable safety risks. This is particularly concerning for structural materials exposed to extreme service environments, such as high temperature, high pressure, extremely acidic/oxidizing, and radioactive conditions. Therefore, it is imperative to develop effective strategies to combat corrosion in these environments.

This talk will focus 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 aggressive environments.
