| Abstract: |
| Plenty of technical problems of traditional micro-arc oxidation equipment are difficult to deal with during application. A new method of local electric-field control was put forward for micro-arc oxidation treatment of large part, which using shielding anode and on the basis of local discharging and putting the integrity into pieces. A local electric-field control micro-arc oxidation equipment with moving cathode was designed and developed, which realized the micro-arc oxidation treatment of large work surface. Moreover, this equipment can be used to repair engineering equipment by treating the corrosion damage of key position with its simple and convenient operation. |
