Summary
Corrosion is a major contributor to structural deterioration in steel structures, leading to increased maintenance costs and reduced reliability. Across the United States, tens of thousands of steel bridges are in poor or fair condition, primarily due to corrosion-related damage. This research project investigates the use of cold spray metal additive manufacturing as a method to restore corroded steel bridge components directly on-site. Unlike traditional repair techniques that require extensive welding, cutting, or complete replacement, cold spray offers the ability to apply new metal onto co
