| 초록 | We are current-voltage curves were measured using cyclic voltammetry. Electrochemical properties and the relationship between surface states of metals were investigated by Scanning Electron Microscope(SEM). We determined electrochemical measurement by using cyclic voltammetry with a three-electrode system. A measuring range was reduced from initial potential to -1350mV, continuously oxidized to 1650 mV and measured to the initial point. The scan rate were 50, 100, 150, 200 and 250 mV/s. As a result, the C-V characterization of metal using monoethanolamine(MEA) as corrosion inhibitor appeared irreversible process caused by the oxidation current from the cyclic voltammogram. Using MEA as corrosion inhibitor in case of increasing the concentration of the electrolyte was decreased diffusion coefficient. SEM images of copper was confirmed by increasing the electrolyte concentration was increased surface corrosion. The corrosion inhibitor of 1.0x10-3 M MEA was used for the electrolyte of 0.1 N and a relatively large diffusion coefficient reduced the effect of preventing corrosion. |
