  • Plasma electrolytic oxidation apparatus and method of plasma electrolytic oxidation using the same
    Patent number: 11555253
    Abstract: In a plasma electrolytic oxidation apparatus and a method of plasma electrolytic oxidation using the plasma electrolytic oxidation apparatus, the plasma electrolytic oxidation apparatus includes a chamber and an electrode unit. The chamber is configured to receive an electrolyte. The electrode unit is configured to receive the electrolyte from the chamber and to treat an object with a plasma electrolytic oxidation treatment. The electrode unit includes an electrode, an enclosing part and a cover. The electrode is configured to receive a voltage from outside, and to form a receiving space in which the electrolyte is received between the electrode and the object. The enclosing part is configured to enclose a gap between the electrode and the object. The cover is configured to cover the electrode.
