摘要

The anodic, chloride ion-facilitated dissolution of copper, wrought 90-10 copper-nickel, and wrought nickel aluminum bronze, in controlled aqueous chloride electrolytes, has been examined at comparatively low values of polarization, i.e., <200 mV relative to the corrosion potential. Laminar flow to a rotating disc electrode (80 < Re^sub RDE^ < 3,800) and turbulent flow around a rotating cylinder electrode (1,920 < Re^sub 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 cuprous dichloride ion formation, and each system showed mixed (charge and mass transport) control of the anodic dissolution.
