In order to develop a novel corrosion inhibitor that is suitable for the 1F environment, it was focused on aluminum lactate, which had not been focused on as a corrosion inhibitor. It was found that aluminum lactate had a synergistic effect and high corrosion inhibition ability when mixed with sodium molybdate. As a result of surface XPS analysis, it was found that the corrosion of carbon steel was inhibited by the formation of aluminum and molybdenum oxide films on the carbon steel surface.
