Abstract

This work has investigated the corrosion performance and mass transfer of oxygen on copper and nickel-aluminium bronze surfaces within a wall-jet flow cell assembly. Limiting currents of the dissolved oxygen mass-transfer kinetics as a function of volume flow rate at a wall-jet electrode were examined for copper and nickel-aluminium bronze in a 3.5 wt.% NaCl solution. Mass transfer kinetics for the reduction process studied was compared with rotating disc and cylinder electrode data. The wall-jet electrode mass transfer coefficients for commercially pure copper and cast nickel-aluminium bronze were determined to be 0.01-0.06 cm s^–1 and 0.01-0.05 cm s^–1, respectively.
