A process method of a magnesium alloy surface super hydrophobic prepared

The invention discloses a process method for preparing superhydrophobic magnesium alloy surfaces, which comprises the following steps that: (1), firstly, a metal magnesium alloy plate is cleaned and deoiled, then, the mechanical polishing is carried out, next, deionized water is used for ultrasonic wave cleaning, and the blowing drying is carried out; (2), the cleanly cleaned magnesium alloy plate is fixed on an anode clamp to be used as an anode, a metal plate with the area dimension smaller than the magnesium alloy plate is fixed on a cathode clamp and is used as a cathode, and electrolyte is filled between the cathode and the anode through an electrolyte circulation system; (3), constant current is introduced between two ends of the cathode and the anode, in addition, the scanning of the cathode on the anode magnesium alloy plate is realized through a feeding control system, and further, a binary micro-nanometer rough structure is processed on the magnesium alloy plate; and (4), after the magnesium alloy surface subjected to electrochemical process is modified by low-surface-energy materials, the superhydrophobic magnesium alloy surface can be obtained. The process method has the advantages that the operation process is simple, the controllability is good, the pollution is little, the cost is low, the acid and the alkali are not needed, and the like, and the process method is suitable for large-scale industrial production.
