Abstract:
A high-speed corrosion-resistant rotating cylinder electrode system for ex situ monitoring of corrosion rates of metals, comprising:an electrochemical/permeation cell body adapted to contain a fluid whose corrosive effect is to be monitored, said cell body having a base at a lower surface thereof and said base having an aperture therethrough; a counter electrode mounted within said cell for introducing an electrical current into the fluid; a reference electrode mounted within said cell and having a fixed potential overtime; a cylindrical working elect ode adapted to be connected to a device for measuring a potential of said working electrode over time; and a rotatable system shaft, connectable to a motor for rotation, having a lower portion below said base and extending therefrom through said aperture into said cell body, said working electrode being mounted n an upper portion of said system shaft to be positioned within said cell body for rotation.
