摘要：

The aim of the present work was to study the influence of surface finishing on the corrosion resistance of AISI 304 stainless steel samples. Samples were submitted to lathe-turning, milling, lapping and grinding. Roughness parameters were determined by confocal laser scanning microscopy (CLSM). The corrosion resistance was evaluated using potentiodynamic polarisation curves and the corrosion morphology was assessed using CLSM and scanning electron microscopy. The results showed that the surface state had a remarkable influence on the corrosion behaviour of the samples, especially surface imperfections, whereas the roughness parameters did not directly correlate with the corrosion resistance.
