This document summarizes an experiment that measured the corrosion resistance of 304 stainless steel samples with different surface treatments. Electrochemical measurements were taken in 3.5% NaCl solution to analyze the corrosion behavior. Samples that were mechanically polished showed the highest corrosion rate. Electropolishing improved corrosion resistance by lowering the corrosion potential and current density. Anodizing further improved corrosion resistance by forming a protective oxide layer, shown by the most negative corrosion potential and lowest current density, as well as the highest pitting potential observed. The results indicate that anodizing 304 stainless steel provides the best protection against corrosion in saline environments.
