Abstract

The invention belongs to the technical field of titanium alloy materials, and discloses an ultralimit titanium alloy and a preparation method thereof. The ultralimit titanium alloy comprises a titanium alloy base body, wherein a composite bonding layer, a composite ceramic layer, a reflecting layer, an anti-refracting layer, an insulating layer and a foamy carbon layer are sequentially deposited on the surface of the titanium alloy base body; the composite bonding layer comprises a bonding layer deposited on the surface of the titanium alloy base body and a noble 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. According to the method, the multiple layers of coatings are deposited on the surface ofthe titanium alloy base body, the use temperature of the titanium alloy can be increased to be higher than the melting point of the original titanium alloy base body by 100-500 DEG C so that the titanium alloy can be used in an untralimit environment. The ultralimit titanium alloy has excellent high-temperature mechanical property and chemical stability, can be used under the condition that the temperature is higher than the titanium alloy base body melting point of the titanium alloy, and the application range is enlarged.

Description

technical field [0001] The invention belongs to the technical field of preparation of titanium alloy materials, and in particular relates to an ultra-limit titanium alloy and a preparation method thereof. Background technique [0002] Titanium alloys have the characteristics of high strength, small specific gravity, good corrosion resistance, high heat resistance, high hardness, and good compatibility with organisms. In the 20th century, titanium-based alloys were widely used in aviation, aerospace, submarines, and medical treatment. In other fields, the first practical titanium alloy was the Ti-6Al-4V alloy successfully developed in the United States in 1954, and then became the ace alloy in the titanium alloy industry. The use of this alloy has accounted for 75% to 85% of all titanium alloys. Many other titanium alloys can be regarded as modifications of Ti-6Al-4V alloy. Titanium alloys can still maintain their mechanical properties at low and ultra-low temperatures. Tit...
