Abstract
A surface treatment method of a magnesium alloy article includes, instead of forming a primer on a magnesium alloy based composite first, directly performing a hairline finish process on the magnesium alloy based composite, to form a hairline structure on a surface of the magnesium alloy based composite, and performing a chemical oxidation process on the magnesium alloy based composite, to form a glossy film covering the hairline structure on the magnesium alloy based composite, thereby forming a magnesium alloy article structure. Alternatively, another chemical oxidation process is performed before the hairline finish process, to form an oxide film on the surface of the magnesium alloy based composite.
Claims11
A surface treatment method of a magnesium alloy article, comprising:
- providing a magnesium alloy based composite without a primer on a surface thereof;
- performing a hairline finish process on the magnesium alloy based composite, to form at least one hairline structure on a surface of the magnesium alloy based composite;
- and
- performing a first chemical oxidation process on the magnesium alloy based composite, to form a glossy film covering the hairline structure on the surface of the magnesium alloy based composite, wherein the glossy film is defined as a surface protection film of the hairline structure, and is used for maintaining or increasing the glossiness of the surface of the magnesium alloy based composite;
- wherein before the hairline finish process, the method further comprises performing a second chemical oxidation process on the magnesium alloy based composite, to form an oxide film on the surface of the magnesium alloy based composite, and the hairline structure penetrates through the oxide film, and is formed on the surface of the magnesium alloy based composite.
