Investigation of Copper Anodization Products with Temperature and Chemical Solution Changes

Abstract

The rapid breakdown anodization (RBA) process was used to modify the copper surface and produce copper oxide powder. The effects of the temperature and inhibitors like glycerol and ethylene glycol were studied. The rate of corrosion increased dramatically at low temperatures, whereas it decreased at high temperatures. Cubic Cu₂O particles were formed on the anode. Their volumes increased with increasing temperatures. Scanning electron microscope (SEM) images show the production of semispherical particles in the powder formed at low temperatures, but these particles congregate and combine at high temperatures. After using the glycerol, octahedron and semispherical Cu₂O particles were formed on the anode and cathode, respectively. The findings confirm the concept that the anodizing process's temperature may be utilized for controlling the oxide to metal ratio. Significant slowing of the anodic process occurs at high ratios for both inhibitors.
