Effects of nickel-aluminum bronze pre-oxidized films on the cathodic kinetics of oxygen reduction
Effects of nickel-aluminum bronze pre-oxidized films on the cathodic kinetics of oxygen reduction
The cathodic oxygen reduction kinetics of the freshly polished and the pre-oxidized nickel-aluminum bronze surfaces were investigated in a 3.5 wt.% NaCl solution under steady-state and well-defined hydrodynamic conditions using a rotating disc electrode setup. The diffusion coefficient of the pre-oxidized film specimen of 0.72 10–5 cm2 s–1, was lower than that of the freshly polished surface of 2.55 10–5 cm2 s–1, a 3.5 fold decrease, demonstrating the extent to which the oxygen diffusion within the pre-oxidized film was hindered.

Abstract
The cathodic oxygen reduction kinetics of the freshly polished and the pre-oxidized nickel-aluminum bronze surfaces were investigated in a 3.5 wt.% NaCl solution under steady-state and well-defined hydrodynamic conditions using a rotating disc electrode setup. The diffusion coefficient of the pre-oxidized film specimen of 0.72 10–5 cm2 s–1, was lower than that of the freshly polished surface of 2.55 10–5 cm2 s–1, a 3.5 fold decrease, demonstrating the extent to which the oxygen diffusion within the pre-oxidized film was hindered.
