Problems solved by technology

Although these methods have a certain anti-corrosion protection effect on magnesium alloys, their anti-corrosion effects are average, which cannot meet the application of magnesium alloys in complex and harsh corrosive environments such as high temperature and high humidity.
[0005] It can be seen from the above that the magnesium alloy plate obtained by the existing processing technology has low strength and poor corrosion resistance, which limits its application range

[0073] The embodiment of the present invention provides a kind of processing method of magnesium alloy plate, such as figure 1 As shown, the method includes:

[0074] Step 101: Add a first preset amount of nanoscale silicon carbide with a target particle size to the magnesium alloy raw material solution, and stir evenly to obtain a target mixed solution.

[0075] Among them, by controlling the total amount of nano-scale silicon carbide added to the magnesium alloy, the strength of the magnesium alloy plate obtained through final processing can be changed. However, the first preset amount added in the embodiment of the present invention is 0.1%-5% of the mass of the magnesium alloy raw material, which can make the magnesium alloy plate obtained by final processing achieve higher strength.

[0076] In addition, preferably, the target particle size is 50 nm to 70 nm. Among them, nano-scale silicon carbide with an average particle size of 50 nanometers to 70 nanometers can be ma...

Abstract

The invention provides a magnesium alloy plate machining method and a magnesium alloy plate. The method comprises the following steps: a first preset quantity of nanoscale silicon carbide with a target particle size is added in solution of a magnesium alloy raw material for uniform stirring to obtain target mixed solution; the target mixed solution is machined as a magnesium alloy ingot; the magnesium alloy ingot is machined as a magnesium alloy plate with a first preset thickness, so that the nanoscale silicon carbide is dispersed in a magnesium alloy crystal; and graphene is sprayed on the surface of the magnesium alloy plate to form a graphene film with a second preset thickness. The nanoscale silicon carbide particles are added in a magnesium alloy to disperse in the magnesium alloy crystal; a graphene corrosion resistant film is sprayed on the surface of the magnesium alloy to obtain the magnesium alloy plate with high strength and corrosion resistance; the application range is widened; and the problems of low strength and weak corrosion resistance in a traditional magnesium alloy plate are solved.

Description

technical field [0001] The invention relates to the technical field of material processing, in particular to a processing method for a magnesium alloy plate and the magnesium alloy plate. Background technique [0002] Magnesium alloy is the lightest alloy among practical metals. Magnesium alloy is 36% lighter than aluminum alloy, 73% lighter than zinc alloy, and 77% lighter than steel. It is the metal with the highest specific strength among practical metals. Among industrial metal materials, magnesium alloy, as the lightest material, is widely used in sporting goods, home appliances, aerospace instruments, machinery manufacturing parts and other products. Among them, although magnesium and magnesium alloys have many excellent properties and wide applications, they also have many defects and deficiencies, such as low strength, poor heat resistance, and poor corrosion resistance, which greatly limit the application range of magnesium and magnesium alloys. In order to apply ...
