Abstract


This  study  presents  a  corrosion  analysis  of  carbon  steel  by  electrochemical  polarization tests on a rotating disk electrode at several aeration and hydrodynamic conditions in  solution  0.2  mol  L-1  K2SO4  at  pH  3.  The  reactions  involved  in  the  dissolution  of  the  steel  are  analyzed  by  studying  the  Tafel  regions  of  the  polarization  curves,  confirming  that  the  dissolved oxygen plays a predominant role in the corrosion of the metal. The corrosion rate was  35  times  higher  in  natural  aeration  conditions  than  in  the  deaerated  medium.  Under  natural aeration conditions, it is not possible to make a simple analysis of the corrosion of the steel from the extrapolation of the Tafel slopes since such slopes were not well defined due  to  the  formation  of  rust  in  the  anodic  region  and  the  influence  of  mass  transport  in  the  cathodic  region.  At  cathodic  polarization  potentials  and  with  natural  aeration,  there  is  an  increase  in  polarization  currents  with  respect  to  the  deaerated  system  and  the  oxygen  reduction  reaction  is  controlled  by  the  mass  transport.  Under  deaerated  conditions  and  at  intermediate polarization potentials, there is a change in the dissolution mechanism of the steel.  At  high  overpotential,  the  rate  of  dissolution  of  the  steel  tends  to  be  equal  in  both  systems,  aerated  and  deaerated  because  the  corrosion  of  the  metal  is  controlled  by  the  diffusion of species through corrosion products film.
