The work was carried out with small coupons immersed in soIw ions containing dWèrent quantities of MaC in presence of various NaNO concentrations w corrosion inhibitors. It has been found that:(I) In presence of NaCI the time required to reach °2 evolution potential in dc-aerated Ca(0h9 polarized at lOpA/cm is function of inhibitor concentration and it becomes lass as NaNO increases compared with zero presence indicating the effectiveness of PIaNO as anodic corrosion inhibitor. (2) In absence of NaC1, the time required to reach 01 evolution potential in de solutions is less that in aerated solutions when inhibitor increases from 0 to 0.3 wt%. (3) In presence of sufficient chloride in dc-aerated Ca(OI-i9, solution, the passive film m broken down locally.
