ELECTROCHEMICAL TREATMENT BASED SURFACE MODIFICATION DEVICE

摘要

The invention provides an electrochemical treatment based surface modification device that comprises a solution tank, a cathode terminal, and an anode terminal. The solution tank is filled with an acidic solution which contains first valence metal ions. The first valence metal ions are partially reduced to second valence metal ions at the cathode terminal. The valence of the first valence metal ion is greater than that of the second valence metal ion. The anode terminal is provided an electrically conductive oxide, and the second valence metal ions move from the cathode terminal to the anode terminal to from a metal oxide. Wherein, the deposition and etching of the conductive oxide occur simultaneously on the surface of the anode.
