Resumo: | Grain size refinement can modify the electrochemical behavior of austenitic stainless steels due the variation of the grain boundaries density. The relationship between grain size and corrosion resistance is not straightforward, motivating several investigations to help clarifying this effect. The aim of the present work was to investigate the effect of grain size on the pitting corrosion resistance of the AISI 304 stainless steel. By exposing samples of this material to different annealing treatments different microstructures with varying grain sizes have been obtained. Potentiodynamic polarization curves were used to evaluate the corrosion behavior of the samples. The results showed that pitting corrosion resistance was increased for the samples with finer grain sizes and this effect is likely due to the formation of a more stable passive film. |
