정류상태(steady state)와 과도상태(transient state)의 Tafel 기울기, 순환 전압-전류 곡선, 임피던스 측정자료에 기초하여 인공해수에서 구리의 부식과 부동화에 대한 반응 메커니즘을 제안하였다. 구리의 산화환원 반응은 인공해수에서의 산소농도와 전극전위에 의존함을 알 수 있었다.

Based on the cyclic voltammograms, potentiodynamic polarizations, transient and steady state Tafel plots and electrochemical impedence spectroscopy, we proposed the copper redox mechanism of the corrosion and passivation in artificial sea water. The copper redox mechanism showed the dependence of the concentration of oxygen in artificial sea water and electrode potentials.
