| 中文摘要 | The effects of oxygen, H(2)SO(4) concentration and surface roughness on the electrochemical behaviour of high nitrogen bearing stainless steel (HNS) in acidified 0.5 M NaCl solution were investigated using potentiodynamic polarization method. The results revealed three corrosion potentials indicating an unstable system. The number of the potentials was influenced by H(2)SO(4) concentration. Three potentials existed above 0.011 M H(2)SO(4), two between 0.011 and 0.0065 M H(2)SO(4) and one below 0.0065 M H(2)SO(4). Oxygen increased the number of corrosion potential at 0.005 M H(2)SO(4) + 0.5 M NaCl solution while surface roughness had no noticeable influence on the number of potentials but increased the values of the corrosion potentials and passivation current densities with increase in the surface roughness. The corrosion mechanism has been discussed using the ideal polarization curve models. (C) 2008 Elsevier Ltd. All rights reserved. |
