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.

镍铝青铜预氧化膜对氧还原阴极动力学的影响

摘要 在 3.5 wt.% NaCl 溶液中，在稳态和明确定义的流体动力学条件下，使用转盘电极装置研究了新抛光和预氧化的镍铝青铜表面的阴极氧还原动力学。0.72 × 10-5 cm2 s-1 的预氧化膜样品的扩散系数低于 2.55 × 10-5 cm2 s-1 的新抛光表面，降低了 3.5 倍，证明了这阻碍了预氧化膜内的氧扩散。
