The Influence of Mechanical and Chemical Surface Treatments on the Passivity of Stainless Steels
The surface finish treatment of stainless steels is done my mechanical or chemical treatments or a combination thereof. The influence of these treatments on the passivation behaviour of austenitic stainless steels 304L and 316L and 22 % Cr duplex stainless steel is studied by electrochemical noise and electrochemical impedance measurements. The surface treatments studied include grinding, blasting, pickling, polishing, electropolishing and anodic electrochemical treatment. The effects of an additional chemical passivation treatment is compared to those obtained by a spontaneous passivation in air and the kinetic effects are studied. The results of standard corrosion tests are correlated to the findings obtained in measurements of surface energies and analysis of passive films by AFM measurements.
