<p>Bridge girder ends were the major weak points against corrosion. Therefore, it is necessary to develop the anticorrosion technique for them. In this study, we focused on Cold Spray technique, which can form a metallic film, as a corrosion protection film-forming method. In this study, we applied the mixed particles of zinc particles and alumina particles to the corroded steel bridge girder ends in the Cold Spray method to verify the corrosion protection performance and field applicability. Cold Spray Corrosion protection technology was applied to the corroded steel bridge girder ends, and corrosion monitoring was performed to verify the effectiveness in a corrosive environment.</p>
