a)Fe is put into aerated water (PH:7). Do you expect corrosion? Explain using Pourbaix diagram of Fe (10-6 line). b) Plot approximately the polarization diagrams
a)Fe is put into aerated water (PH:7). Do you expect corrosion? Explain using Pourbaix diagram of Fe (10-6 line). b) Plot approximately the polarization diagrams using Pourbaix diagram of Fe (10-6 line) and assuming complete activation control polarization with the same tafel slopes. Show halfcell revesible potentials, cell potential, the corrosion rate and potential. Write anodic and cathodic reactions. What is the driving force for corrosion? c) Explain briefly the concentration polarization and discuss qualitatively the effect of stirring of solution on the corrosion potential and corrosion rate in part (b) using the equations below (what are the terms in the equations-sketch it): iL=DznFCB/
