Abstract

The invention provides a surface spraying liquid for a magnesium workpiece and a method for preparing a durable superamphiphobic surface of a magnesium workpiece by using the spraying liquid. The magnesium workpiece surface spraying liquid of the present invention does not contain fluorine, silicon, rubber, resin and various micro / nano fillers, and the components are environmentally friendly and do not cause compatibility problems; the spraying liquid is evenly sprayed onto the clean magnesium workpiece surface, and then The durable superamphiphobic surface of the magnesium workpiece can be obtained through proper curing treatment. The superamphiphobic surface of the magnesium workpiece prepared by the invention has good durability, and can withstand various severe tests such as friction and wear, ultraviolet radiation, high-pressure water column impact, strong acid and strong alkali, organic solvent immersion, strong corrosive medium immersion, etc., and is expected to greatly broaden the scope of magnesium materials. field of application. The method of the invention is applicable to the treatment of magnesium and its alloy workpieces of various sizes and shapes. The method of the invention has the characteristics of simple process, convenient operation, environmental protection, easy large-scale industrialized treatment and the like.

Description

technical field [0001] The invention belongs to the technical field of surface engineering, and in particular relates to a surface spraying liquid for magnesium workpieces and a method for preparing durable superamphiphobic surfaces of magnesium workpieces. Background technique [0002] Magnesium material has the advantages of high specific strength, specific stiffness, damping, machinability, thermal conductivity, strong electromagnetic shielding ability, etc., and is known as "the most promising green engineering material in the 21st century". with broadly application foreground. However, its chemical properties are very active, and the natural oxide film on its surface is loose and porous, and basically has no protective effect. Therefore, it is necessary to improve the durability of the magnesium alloy surface through appropriate surface treatment to promote its wide application. [0003] Due to its special wettability of both superhydrophobic and superoleophobic, compa...
