摘要：

Zircaloy samples were oxidized in water vapour at 400-degrees-C and 105 bar for up to 90 days. The samples were then studied by EIS in 0.5M K2SO4 at 20-200-degrees-C (1-15 bar). Evaluation yields data about layer thickness, irreversible penetration of electrolyte into pores aided by increasing pressure, activation energies of transport processes from the temperature dependence of kinetic parameters.
