Abstract

The invention relates to the technical field of metal material surface treatment, and particularly relates to a surface treatment process of a magnesium alloy product. The surface treatment process comprises the following processing steps: (1) removing greasy dirt on the surface of a magnesium alloy workpiece; (2) removing an oxide on the surface of the magnesium alloy workpiece; (3) processing the magnesium alloy workpiece in a surface treating agent solution; (4) carrying out cathode electrophoretic painting on the magnesium alloy workpiece; (5) solidifying and baking the workpiece after electrophoretic painting. The component formula of the treating agent in the surface treatment process of the magnesium alloy product provided by the technical scheme disclosed by the invention is wide in raw material source, low in cost, stable in bath solution, not easy in generation of sediments, safe and environment-friendly in component in the use procedure, the late solderability of the magnesium alloy metal product is not affected, and the surface treatment process of the magnesium alloy product is simple, applicable to treatment of the surface of the magnesium alloy metal product, convenient and practical, and applicable to popularization and application.

Description

technical field

[0001] The invention relates to the technical field of surface treatment of metal materials, in particular to a surface treatment process of magnesium alloy products. Background technique

[0002] Magnesium alloy is a common alloy material in daily life. The main alloy elements are aluminum, zinc, manganese, cerium, thorium, and a small amount of zirconium or cadmium. Magnesium alloy has good machinability, high specific strength, good shock absorption ability, and electromagnetic shielding. Good performance, excellent hydrogen storage performance, good thermal conductivity, high die-casting productivity, easy cutting, easy recycling, etc., is a light metal structural material with superior performance, and has great potential in industries such as aviation, aerospace, electronics, automobiles, and medical equipment. widely used. However, magnesium has the characteristics of poor corrosion resistance, and magnesium alloys have the disadvantage of being easil...
