The aim of this work is to investigate the influence of different types of surface finishes to stainless steel of quality AISI 440 on the corrosion properties of this steel. In order to accomplish this goal, tests are performed on surface finishes in two different environments: in an NaCl aqueous solution, and in acetic acid. In addition to the methods used, surface roughness is also measured, and XRD, SEM-EDS surface analyses are performed. Based on the results of the performed analyses, it was found that, in the NaCl solution, the pitting potential depends strongly on the surface roughness and the surface finish. The evolution of the passive films on Martensitic 440 stainless steel in seawater and in pure 3.5 % NaCl and 3.5% acetic acid is studied using Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS).
