Magnesium keronite method for improving corrosion resistance

摘要

The present invention relates to a magnesium anodizing method comprising a pre-processing step for pre-processing a magnesium plate; a Keronite process and CNT submerging step for applying voltage of 300-700 V to Keronite electrolyte after the pre-processing step, making plasma reaction by inserting the magnesium plate into the electrolyte, forming a porous film layer having multiple pores on the surface of the magnesium plate, and permeating a hydrophilic CNT particle into the pores of the porous film layer; and a drying step for evaporating or drying moisture which remains on the surface of the magnesium plate after removing foreign substances generated in the CNT submerging step.
