초록

In this study, anti-tarnishing and corrosion characteristics of a single β1ʹ and Bangjja Yugi alloy in the Cl ion environment before and after potentiostatic electrolysis treatment were compared. Stable and uniform SnO2 oxide film with several nanometer thickness is formed after potentiostatic electrolysis treatment. In the case of Bangjja Yugi prior to potentiostatic electrolysis (PE) treatment for exposure in Cl environment, tarnishing occurs rapidly within 0.5hr, whereas PE treated Bangjja Yugi indicates stable surface without tarnishing up to 3hr.
Especially, it is noticeable that anti-tarnishing and corrosion characteristic of PE treated single β1ʹ, which were significantly improved by 3 times and 15 times, respectively, compared to conventional Bangja Yugi.
