Abstract

The present invention relates to a magnesium alloy material surface treating solution and a magnesium alloy material surface treating technology, and is characterized by comprising the following procedures: the metal surface is cleaned according to the usual surface cleaning method of magnesium alloy; the magnesium alloy material is rapidly transferred to a treating solution to be immersed for 0.5 min to 1.0 min and is hot-air dried under the temperature between 50 DEG C and 70 DEG C; a protective film is formed on the surface of the magnesium alloy material. A layer of exquisite, tight and colorful film is formed on the surface of the magnesium alloy with the technique of the invention, thereby achieving a certain decorative effect. The invention can not only have short-term protection on magnesium alloy but also improve the binding force and the corrosion resistance between the organic coating layer and the magnesium alloy substrate.

Description

technical field [0001] The invention relates to a surface treatment process, in particular to a surface treatment process of a magnesium alloy material and a treatment solution used in the surface treatment process of the magnesium alloy material. Background technique [0002] As the metal structure material with the lowest density in industrial applications, magnesium alloy has high specific strength, specific stiffness, good casting, shock absorption, cutting, dimensional stability and excellent electromagnetic shielding properties. Due to the improvement of production quality and performance and the decline of production cost and price, the application and research focus of magnesium alloys has expanded from military industry, aviation industry and other fields to civilian (such as automobile and electronics, etc.) industrial fields. In recent years, the application growth rate of magnesium alloy in automobile and electronic industry is as high as 15%-20% / year. The appli...
