Embodiment 1

[0034]This example provides a preparation method for in-situ synthesis of titanium carbide reinforced titanium-based porous materials, the process of which refers to figure 1 As shown, the main steps include the following:

[0035] (1) Ingredients:

[0036] Weigh 2 parts by weight of carbon powder and 98 parts by weight of titanium powder to form a mixed powder with a total weight of 100 parts by weight, and add urea with the same volume as the 100 parts by weight of mixed powder, mix in the research body, and in the mixing process Add absolute ethanol according to the ratio of 5~10ml of absolute ethanol per kilogram of carbon powder, titanium powder and urea mixture; the addition of absolute ethanol is conducive to the uniform mixing of urea, titanium powder and carbon powder, thereby changing the sintering process. The pore structure of the bulk porous titanium-based composite material, but if too much absolute ethanol is added, it is also not conducive to the mixing of ure...

Description

technical field [0001] The invention relates to the technical field of metal foam materials, in particular to a preparation method for in-situ synthesis of titanium carbide reinforced titanium-based porous materials. Background technique [0002] The porosity of the material endows the porous material with new and excellent properties, making it have uses that the dense material cannot match, thus expanding the research field and application range of the foam material. The porous titanium matrix composite material (TMC for short) is a composite material composed of metal titanium as a matrix and adding some second phase material as a reinforcement. Compared with traditional titanium alloys, titanium matrix composites can be further improved in specific strength and specific modulus, excellent creep resistance and fatigue resistance, as well as excellent high temperature performance and corrosion resistance. Titanium-based composite materials improve wear resistance and heat...
