Stainless steel is a metal that does not generate rust. Due to its excellent workability, economic feasibility,and corrosion resistance, it is used in various industrial fields such as ships, piping, nuclear power, andmachinery. However, stainless steel is vulnerable to corrosion in harsh environments. To solve this problem,its corrosion resistance could be improved by electrochemically forming an anodized film on its surface. Inthis study, 316L stainless steel was anodized at room temperature with ethylene glycol-based 0.1 M NH4Fand 0.1M H2O electrolyte to adjust the thickness of the oxide film using different anodic oxidation voltages(30 V, 50 V, and 70 V) with time control. The anodic oxidation experiment was performed by increasingthe time from 1 hour to 7 hours at 2-hour intervals. Corrosion resistance according to the thickness of theanodic oxide film was observed. Electrochemical corrosion behavior of oxide films was investigatedthrough polarization experiments.
