Abstract

The invention discloses a long carbon fiber reinforced titanium alloy composite material. After compounding modified long carbon fibers and titanium alloy powder, the long carbon fiber reinforced titanium alloy composite is prepared by coating with a coating liquid, and then spraying with an anti-corrosion coating. After the coating liquid is treated at high temperature, a metal-ceramic protective film will be formed on the surface of the composite sheet. The protective film can prevent the long carbon fiber reinforced titanium alloy composite material from directly contacting with corrosive substances, ensuring that the material is not easily corroded , the polyaniline in the anti-corrosion coating itself has a good corrosion resistance effect, and the compounding with the intermediate 3 makes the corrosion resistance effect further improved, and the benzotriazole and 2-aminobenzimidazole structures on the intermediate 3, It can coordinate with the copper ions generated by the copper powder in the cermet protective film, which increases the connection between the anti-corrosion coating and the cermet protective film, and greatly improves the corrosion resistance of the long carbon fiber reinforced titanium alloy composite material.

Description

technical field [0001] The invention relates to the technical field of composite alloy material preparation, in particular to a long carbon fiber reinforced titanium alloy composite material. Background technique [0002] Compared with traditional titanium alloys with high specific strength, specific stiffness and specific elastic modulus, carbon fiber reinforced titanium alloy composites have the advantages of high tensile strength, fatigue resistance, wear resistance, corrosion resistance and low density. By adjusting the distribution of carbon fibers in titanium alloys and the bonding between carbon fibers and titanium alloys within a certain range, it is an important high-performance lightweight structural material in the fields of aerospace, ships, automobiles, and equipment preparation. . [0003] Although the corrosion resistance of carbon fiber reinforced titanium alloy composites is much higher than that of traditional single metals, during long-term use, a large a...
