Micro-arc oxidation (MAO) of magnesium alloys is a plasma discharge that occurs at the metal/electrolyte interface when the applied voltage exceeds a certain critical breakdown value. This article in uses for reference had in the chemical reagent formula composition allocated proportion foundation, the reference preliminary attempt test result, through increases the SiC powder in the existing linear element oxidation formula composition (particle size≤5μm), and has carried on the optimization to its technol...
