Abstract

The invention provides a magnesium alloy surface anticorrosive treatment method, which comprises the following steps of: providing a magnesium alloy matrix; chemically deoiling the magnesium alloy matrix; performing chemical conversion treatment on the magnesium alloy matrix by using a solution taking plant oleic acid as a film forming agent, so that a layer of plant oleic acid conversion film is formed on the magnesium alloy matrix; and forming a ceramic coating consisting of infusible compounds on the plant oleic acid conversion film by using a vacuum coating method. The invention provides a magnesium product prepared by the anticorrosive method.

Description

technical field

[0001] The invention relates to a magnesium alloy surface anticorrosion treatment method and magnesium products thereof. Background technique

[0002] Magnesium alloys have the advantages of light weight and good heat dissipation, and are widely used in communications, electronics, transportation, construction, aerospace and other fields. However, due to the high chemical activity of magnesium alloys, it is easy to oxidize in the air, forming a loose and poorly protective oxide film, which leads to severe corrosion of magnesium alloys in humid atmosphere, soil and seawater, which leads to the use of magnesium alloys to make The life of the products is shortened, which hinders the wide application of magnesium alloys.

[0003] In order to improve the corrosion resistance of magnesium alloys, it is usually necessary to carry out surface film-forming treatment on the surface of magnesium alloys. The common treatment methods include anodic oxidation treatment, b...
