The study tested the change of corrosion current density and mass corrosion coefficient of heat treatable (isothermally quenched and artificially aged) wrought Al-Si-Mg-Cu alloy depending on isothermal soaking steps of different duration. The findings of the research illustrate that the dependence of corrosion current density on isothermal soaking step has the extreme character and is determined not only by the. isothermal soaking step duration and its temperature but also by the features of a secondary crystallization process in over saturated solid solution decompoition and kinetics of electrochemical corrosion.
