Abstract
The mechanism of the initial corrosion of copper in hydrochloric acid solutions has been investigated, using a radioactive tracer technique. Kinetic data have been obtained showing the effect of pH, dissolved oxygen, chloride ion, and temperature on the corrosion rate. Surface areas were measured using a modified electrolytic method. On the basis of these data (reproducible to ± 20%), a mechanism for the initial corrosion process is proposed and discussed. Specific rate constants, heats, and entropies of activation for the slow step in the corrosion process were determined.Keywords
