MANIFACTURING FOR OXIDIZED LAYER OF MAGNESIUM-BASED METAL MATERIAL

摘要

PURPOSE: A method for manufacturing an oxide layer of Mg-based metal is provided to form a fine oxide layer on the surface of a Mg alloy and Mg with a dry type surface treatment method using arc plasma, thereby improving corrosion resistance. CONSTITUTION: A method for manufacturing an oxide layer of Mg-based parent metal includes the following steps of: preparing Mg-based parent metal; forming a H2O layer on the surface of the Mg-based parent metal; and forming an oxide layer on the Mg-based parent metal by radiating plasma using source gas to the Mg-based parent metal.
