Abstract

The invention discloses a preparation method of a micro-arc oxidation electrolyte. The preparation method comprises the steps that film-forming agents of 5-10 g/L and auxiliary film-forming agents of 1-5 g/L are added into a container, and mixed liquor is formed; then a PH value conditioning agent is added into the mixed liquor so that the mixed liquor can be alkalescent; conductivity conditioning agents of 0.067-0.567 g/L are added, and are evenly dispersed in the electrolyte through an ultrasonic device of micro-arc oxidation equipment; and finally stabilizers of 5-30 ml/L are added to adjust the conductivity of the electrolyte to a proper value, and the micro-arc oxidation electrolyte is obtained through preparation. According to the preparation method, the big problems that an existing micro-arc oxidation electrolyte is high in energy consumption, low in efficiency and short in service life, and environment is polluted by components can be solved.

Description

technical field [0001] The invention relates to the technical field of metal surface modification, in particular to a configuration method of a micro-arc oxidation electrolyte. Background technique [0002] Light metal aluminum, magnesium, and titanium have the advantages of high specific strength, good thermal and electrical conductivity, strong reflectivity, beautiful color, good plasticity and formability, and no low-temperature brittleness. They are non-ferrous metal materials with excellent comprehensive properties. At present, the disadvantages of light metal alloy materials are that the surface of the alloy is soft, not resistant to wear, not resistant to high temperature, and the corrosion resistance of the alloy is insufficient under special conditions. Among them, the corrosion potential of aluminum is low, and the overall corrosion is more serious. For example, the natural oxide film formed by metal aluminum has poor corrosion resistance, and it is prone to interg...
