✦ Synopsis

The polarization b&&our of Arrnco iron in anhydrous solutions of CH,OH+HCI and CH,OH + HCl + LiCl was studied by the potentiostatic method. The following reaction orders were found for the anodic process: Z,(,,-) = 1.7-1.82 and Z,(,+) = 0. The following mechanism of dissolution is proposed: Fe +Cl-+FeCl,, F&l2 + Cl--t FeCl, f 2e (rate-determining step), F&l, *Fez+ +2Cl-.

The rate of dissolution of Armco Fe has been measured as a function of time for deaerated solutions of constant ionic strengtb (HCl + NaCl). For pH < 1.5, no appreciable change of the measured polarisation resistance was observed. For 1.5 -=I pH < 3 the polarisation resistance gave straight lines w

The kinetics of the layer formation process and the corrosion process have been determined from the relation between the stationary (i,J and non-stationary (i,) corrosion rates and the rate of layer formation (it) at passive iron in acid solutions. The rates of both processes depend on the poten- ti
