Special rings with iridescent color were found around erosion pits on mild carbon steel surface in rotate disk cavitation erosion experiments. The EDS and XPS examinations proved that the ring was an oxidation film mainly composed of Fe 2 O 3 . The mean diameter of iridescent rings was 200-300 m, an
