Comparative Studying of Marine Parameters’ Effect, via Qualitative Method

In this study the marine corrosion resistivity of the austenitic stainless steels type 304 and 316 has been studied qualitatively. This study is under the synergistic effect of environmental factors. Salinity, velocity, pH and temperature are the factors which induce effects. Corrosion rates are calculated in aerated synthetic seawater, via potentiodynamic polarization scan. Qualitative analysis has been used to predict the variation direction of corrosion rate while applying the most important marine parameters, synergistically. This analysis has an important role in marine applications and predicts the individual effect of considered parameters, as well as their synergistic action effect on the rate of corrosion.
