PURPOSE: A method for manufacturing an oxide layer of a Mg-based metal is provided to form an oxide layer of thickness enough to protect the Mg-base metal without generating waste water, thereby eco-friendly forming the oxide layer. CONSTITUTION: A method for manufacturing an oxide layer of a Mg-based metal includes a chamber, a plasma generating unit (400), a cathode supply unit, a source supply unit, and a high-temperature gas supply unit. The chamber receives a Mg-based parent metal (60), and plasma is generated by the plasma generating unit so that the Mg-based parent metal is irradiated with the plasma. The cathode supply unit applies cathode to the Mg-based parent metal so that arc is formed on the surface of the Mg-based parent metal. The source supply unit supplies source gas to the plasma generating unit. The source gas includes one or more kinds of nitrogen, oxygen, and air. |
