Abstract

The invention discloses a method for plating a magnesium alloy based on an ionic liquid plating solution, relates to the technical field of magnesium alloy surface treatment, and in particular relates to the plating of the pre-plated magnesium alloy in a plating solution in which deep eutectic solvent serves as a solvent. A plated layer obtained through the method is uniform and compact and can be firmly combined with a matrix, and the whole process has the characteristics of simple process, environmental friendliness and the like.

Description

[0001] technical field [0002] The invention relates to a magnesium alloy electroplating method, in particular to a magnesium alloy electroplating method based on an ionic liquid electroplating solution. Background technique [0003] Magnesium alloy has the characteristics of high specific strength, good thermal conductivity, die-casting thin-walled devices, and easy recycling. It is one of the most potential structural materials for development and application. It is widely used in many fields such as aviation industry, electronics industry, and automobile industry. application prospects. However, the chemical properties of magnesium alloys are extremely active and their corrosion resistance is poor, and they are particularly prone to chemical reactions with water and are corroded. This is the key issue hindering its widespread application. Therefore, in order to use magnesium alloys in various environments, it is necessary to develop surface treatment technology for mag...
