Understanding and Laboratory Prediction of the Atmospheric Corrosion Behavior of Steels and of Non-Ferrous Metals and Alloys.
Abstract
This work is based on two important developments in atmospheric corrosion: -an accelerated test method using electrochemical measurements during cyclic immersion tests is interesting for studies of corrosion mechanisms and comparison of behavior in typical and well controlled simulated atmospheric environments, and, -a linear relationship log p = A + B log t between the log of the corrosion penetration and the log of time is recognized as valid for a number of materials. Two major aims of this work were to see if this linear bilog law applies to the atmospheric corrosion of high strength aluminum alloys and to investigate if the electrochemical measurements made in the accelerated test method provide indications on the A and B factors of the corresponding bilog law. Problems were encountered with the validity of such a linear bilog law because of the localized character (pitting and intergranular) of corrosion in some material-environment combinations.
