Abstract

The invention relates to a method for manufacturing a micronanostructure on the surface of a metal, in particular to the method for manufacturing the micronanostructure on the surface of a crystalline magnesium alloy by combining local heating and plasticity duplicating. The method is characterized by comprising the following steps of: performing superfine crystallization on the surface of the crystalline magnesium alloy; and then heating the surface of the crystalline magnesium alloy, which is subjected to superfine crystallization, to a superplasticity temperature range, and grinding the surface of the crystalline magnesium alloy in accordance with the temperature condition with a primarily processed die with the micronanostructure, so that the micronanostructure is quickly duplicated on the surface of the crystalline magnesium alloy. Because the contact time of a heating roller and the surface of the material is short, the whole quality of the metal material is not affected; because after being processed, the roller-shaped die can be repeatedly used for multiple times and special equipment and technique in a surface manufacturing process are not required, the processing cost isgreatly reduced; once the roller-shaped die is processed, the new surface with the micronanostructure is quickly manufactured when the surface is manufactured practically and then the processing efficiency is greatly improved.

Description

technical field [0001] The invention relates to a method for fabricating a micro-nano structure on a metal surface, in particular to a method for fabricating a micro-nano structure on the surface of a crystalline magnesium alloy by combining local heating and plastic replication. Background technique [0002] Magnesium alloy has the advantages of low density, high specific strength, easy processing, good impact resistance, and excellent electromagnetic shielding performance, but at the same time, the material is flammable and poor in corrosion resistance. [0003] In order to improve the corrosion resistance of magnesium alloys, researchers have proposed various methods, mainly including chemical conversion, anodic oxidation, electroplating and chemical plating, liquid phase deposition and sol-gel method, etc.; Oxide or metal compound passivation film is formed on the surface, the chemical conversion film is thin and the binding force is weak, which can only slow down the co...
