| Abstract: | Calcareous deposits that formed in artificial sea water upon Z-35 steel polarized either potentiostatically,galvanostatically, or by a mixed-mode technique(initially galvanostatic followed by potentiostatic) have been performed.Based upon the maintenance current density for the samples with respect to 0-90V(SCE) within the time set for the experiments and the SEM morphology of those samples,it is shown that the deposits formed by the mixed-mode cathodic polarization provide better protective properties.The optimum value of the initial applied polarization current density is found to be slightly greater than the limiting diffusion current density and the relevant turned-over potential to be a little more negative than the final applied protection potential. |
