Research Progress in Corrosion Behavior of Materials Processed by Ultrasonic Rolling

Before and after rolling, the properties of metal surface change, the grain is refined, and the hardness and wear resistance of metal are increased, but the corrosion resistance of related metals is unknown. The corrosion resistance of different metals before and after rolling was discussed. The factors affecting the corrosion resistance of metals were analyzed,and the reasons for the difference of corrosion resistance of different metals were summarized.
