Growth of Etch Pits on Aluminium Cathode Film for Aluminum Electrolytic Capacitor during AC Etching |
| 초록 |
The aluminum electrolytic capacitor is one of the electric parts gathering electricity. Itis used in the wide areas such as photo flash inverter circuit, cars and trains. The wider surface of the aluminum foil, electrochemically very important and it is necessary to increase the surface area. A study has been made of the fabrication condition for etching cube texture of high purity aluminium foil and of electrochemical etching of the aluminium foil. In the present work, it is shown there exists a relation between the influence of the pre-treatment time in the NaOH & HCl solution and H2SO4 concentration in the conversion solution. Also effect of temperature during AC etching was also studied. Result of the etched aluminum film is shown in the typical SEM images. |
