Cover: Local SEM morphologies of 304SS with different machined roughness after an immersion test: (a) and (b) Ra3.2, (c) and (d) Ra6.0. Comparing Figures (a) and (c), it shows that the number of small pits decreases with increasing machined surface roughness. Figures (b) and (d) show that the pits initiated mainly on both sides of the peak ribs and rarely in the valleys.
