In this research, it was evaluated the influence of the current density and sodium hypochlorite dose on the corrosion resistance of AISI 304 stainless steel protected cathodically with impressed current, when was submerged in natural seawater contaminated with sodium hypochlorite. For data collection, rectangular specimen of AISI 304 stainless steel, with dimensions of 50x25x1 mm, were immersed in a solution of seawater with a sodium hypochlorite dose of 5, 10 and 15 mL/L, applying cathodic impressed current, for a period of 7 days with constant agitation. The corrosion resistance of these materials was determinated by pitting count according to ASTM G 46-94. Finally, it was established that AISI 304 stainless steel, immersed in natural sea water contaminated with sodium hypochlorite, requires a current density in the range of 750 to 950 mA/m2 with a sodium hypochlorite dose of 15 mL/L t...
