The corrosion-fatigue behaviour of iron is investigated from an electro-chemical point of view. A good correlation exists in many cases between corrosion electrochemical measurements (Ecorr evolution vs time, polarization curves, polarization resistance evolution vs time) on a fatigue stressed specimen and its behaviour. A discussion of the considered electrochemical parameters and their application to corrosion-fatigue studies is also presented. New data on the corrosion-fatigue behaviour of steel in saturated Ca(OH)2 solutions are reported. This environment simulates the conditions existing within concrete.

Abstract
The corrosion-fatigue behaviour of iron is investigated from an electro-chemical point of view. A good correlation exists in many cases between corrosion electrochemical measurements (Ecorr evolution vs time, polarization curves, polarization resistance evolution vs time) on a fatigue stressed specimen and its behaviour. A discussion of the considered electrochemical parameters and their application to corrosion-fatigue studies is also presented. New data on the corrosion-fatigue behaviour of steel in saturated Ca(OH)2 solutions are reported. This environment simulates the conditions existing within concrete. The detrimental effect of the presence of chloride ions is also discussed. © 1983.
