Cutsets are calculated for the Zn-Fe-O system phase diagram at 700 and 298 K and the Zn-Fe-H2O system potential-pH diagram at 298 K, 1 atm (air), and a i = 10−6 mol/l with zinc excess (C Zn al > C Zn cr ) or deficiency (C Zn al < C Zn cr ) in the alloy surface layer of the Zn-Fe alloy. Thermodynamics of corrosion-electrochemical behavior of different phases in thermal-diffusion zinc coatings are discussed.
