Abstract

The instantaneous corrosion rate has been derived from current–time recordings obtained by electrochemical atmospheric corrosion monitors (EACMs) of aluminium, copper, iron, and zinc subjected to the action of 400μm thick layers of water and 10⁻⁴, 10⁻³, 10⁻², and 10⁻¹ N H₂SO₄ solutions. Anodic polarisation curves were then obtained. Polarisatioh resistance was also measured and polarisation curves plotted for monitors with invisible layers of adsorbed moisture precorroded in the above mentioned solutions. With the EACMs it is possible to study the initial moments of corrosion, showing, for instance, a very rapid reduction in the kinetics of corrosion in some cases with copper and zinc monitors and the appearance of breakdown potentials by medium or high polarisation in others.
