Slotless micro-arc oxidation treatment technology and movable type device of magnesium alloy

The invention discloses a slotless micro-arc oxidation treatment technology and movable type device of a magnesium alloy. The technology comprises the following steps that (1), a to-be-treated magnesium alloy workpiece is taken to conduct pretreatment; (2), one end of the magnesium alloy workpiece is in conductive connection with a power supply positive pole; (3), an electric pole is taken, one end of the electric pole is in conductive connection with a power supply negative pole, and the other end of the electric pole adsorbs a bath solution; (4), a power supply is switched on, the end, adsorbing the bath solution, of the electric pole presses the surface of the magnesium alloy workpiece and is moved to form an oxidation film layer on the surface of the magnesium alloy workpiece; and (5), after the treated magnesium alloy workpiece and electric pole in the step (4) are subjected to washing through water, wipe-drying and blow-drying, follow-up lacquer spraying operation can be conducted. The treatment technol
