Abstract

The invention belongs to the technical field of magnesium alloy metal materials, and discloses an ultralimit magnesium alloy and a preparation method thereof. The ultralimit magnesium alloy comprisesa magnesium alloy matrix, and an anti-oxidation composite bonding layer, a composite ceramic layer, a reflective layer, an anti-refraction layer, an insulating layer and a foamed carbon layer are sequentially deposited to the surface of the magnesium alloy matrix; the anti-oxidation composite bonding layer comprises a bonding layer deposited on the surface of the magnesium alloy matrix and a precious metal layer deposited on the surface of the bonding layer; and the composite ceramic layer comprises a ceramic layer A and a ceramic layer B. During preparation, the anti-oxidation composite bonding layer, the composite ceramic layer, the reflective layer, the anti-refraction layer, the insulating layer and the foamed carbon layer are sequentially deposited on the surface of the magnesium alloy to form the ultralimit magnesium alloy. The use temperature of the ultralimit magnesium alloy is increased to be higher than the melting point of the original magnesium alloy by 100 DEG C to 500 DEGC, and the ultralimit magnesium alloy can be used at the ultralimit temperature.

Description

technical field [0001] The invention belongs to the field of magnesium alloy metal materials, and in particular relates to an ultra-limit magnesium alloy and a preparation method thereof. Background technique [0002] As an important metal material today, magnesium alloy has a low density (1.8g / cm 3 Left and right), high strength, large elastic modulus, good heat dissipation, good shock absorption, high impact load capacity ratio, good corrosion resistance to organic matter and alkali, etc., mainly used in aviation, aerospace, transportation, chemical industry, rockets and other industrial sectors. Magnesium alloy is the lightest metal structural material used in aircraft, spacecraft and rocket missile manufacturing industry, mainly used to manufacture low-load bearing parts. [0003] With the development of technology and the actual needs of the society, the requirements for the speed of the aircraft are getting higher and higher. The speed of the aircraft means that the ...
