A ROTATING-DISK ELECTRODE WITH HEAT-TRANSFER FACILITIES FOR CORROSION STUDIES

A rotating disc electrode allows the study of the effect of controlled mass transfer on the rates of suitable electrochemical and corrosion processes. In practice many corrosion situations involve the added interaction of a heat flux. The construction of a rotating disc electrode with integral controlled heat transfer facilities is described and the technique for determination of the interfacial temperature is shown. Such an assembly allows control of heat and mass transfer, is relatively easy to set up and enables a large throughput of specimens consistent with the needs of an integrated study of the effects of heat and mass transfer on electrochemical and corrosion processes.
