Embodiment Construction

[0010] The specific implementation of a magnesium alloy surface treatment method according to the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0011] see figure 1 , which shows a process flow diagram of a magnesium alloy surface treatment method of the present invention.

[0012] A method for surface treatment of a magnesium alloy according to the present invention is characterized in that it mainly comprises the following steps:

[0013] Step 101: wire-drawing the surface of the magnesium alloy workpiece;

[0014] Step 102: Vacuum sputtering a layer of aluminum film on the surface of the magnesium alloy workpiece after the wire drawing treatment, so as to enhance the metallic texture of the surface of the magnesium alloy product;

[0015] Step 103: Spray transparent varnish on the aluminum-coated layer of the magnesium alloy workpiece, and then bake it in an environment of 150°C for 20-30 minutes. The transpare...

Abstract

The invention provides a surface treatment method for a magnesium alloy. The surface treatment method is characterized by comprising the steps as follows: (1) drawing treatment: a drawing treatment is carried out for the surface of a magnesium alloy piece; (2) vacuum sputtering: a layer of metallic film is coated on the surface of the magnesium alloy piece in a vacuum sputtering manner; and (3) gloss oil spraying: a gloss oil is sprayed on the metallic film on the magnesium alloy piece. Compared with the prior art, the surface treatment method for the magnesium alloy, which is provided by the invention, adopts a technique integrating the drawing treatment, the vacuum sputtering and the gloss oil spraying, thus the surface of the treated magnesium alloy is provided with metallic tactile sensation and can meet demands.

Description

【Technical field】 [0001] The invention relates to a magnesium alloy surface treatment process, in particular to a magnesium alloy surface treatment method with a metallic appearance. 【Background technique】 [0002] Magnesium alloys are light in weight, strong in ductility, and have excellent shock absorption and casting properties. They are widely used in auto parts and 3C industries. When traditional magnesium alloy products are used as exterior parts, they are usually finished by surface spraying, but surface spraying treatment usually cannot maintain the metallic appearance of magnesium alloy products. 【Content of invention】 [0003] In view of this, the purpose of the present invention is to provide a magnesium alloy surface treatment method with a metallic appearance. [0004] In order to achieve the above object, the present invention provides a magnesium alloy surface treatment method, which is characterized in that it mainly includes the following steps: [0005]...
