description	The invention relates to the field of material surface treatment, in particular to a magnesium alloy ultra-high porosity micro-arc oxidation coating and a preparation method and application thereof. After magnesium alloy is sequentially subjected to pretreatment, ultrasonic cleaning, barrier film preparation, cathode micro-arc electro-deposition treatment and anode micro-arc oxidation treatment, an ultrahigh-porosity micro-arc oxidation coating with excellent bonding strength and mechanical performance can be prepared on the surface of the alloy, the porosity of the micro-arc oxidation coating is not lower than 50%, and the micropore diameter is 0.5-3 microns. According to the method, all the steps are carried out in a pressing mode, the target is clear, the respective advantages of cathode micro-arc electro-deposition treatment and anode micro-arc oxidation treatment are fully combined, the high-quality target coating can be formed only through one set of power source device, and a new thought is provided fo
