Laminar flow to a rotating disc electrode (80 <Re rde < 3,800) and turbulent flow around a rotating cylinder electrode (1.920 <Re rce <26,100) were considered at low values of anodic polarization. Using diagnostic factors that were previously developed for unalloyed copper, the dissolution characteristics of the materials have been compared in a systematic manner. A kinetic model, in conjunction with convective-diffusion theory, has been applied to describe the general behavior of all three materials. The chloride ion facilitated a relatively rapid rate of dissolution via cruprous dichloride ion formation, and each system showed mixed (charge and mass transport) control of the anodic disolution. 1 Corrosion 65 ARTICULO Kear, G. 33062 Barker, B.D. 33063 Stokes, K.R. 40172 168889 168889 0 0 0 0 236708 BAAB BAAB 2026-03-05 200043677 0 200043677 2026-03-05 15:11:07 2026-03-05 ARTICULO
