Abstract

The invention discloses a nanometer onion carbon enhanced titanium-based composite material and a preparation method thereof. The composite material is mainly prepared from nanometer onion carbon andbase body titanium, wherein the nanometer onion carbon is used as an enhancing phase and is uniformly distributed in the metal titanium base body to achieve a diffusion enhancing effect. The inventionalso discloses a preparation method of the nanometer onion carbon enhanced titanium-based composite material. By aiming at the defects in the prior art, nanometer diamond is used as raw materials tosynthesize the nanometer onion carbon; the nanometer onion carbon is added into the titanium base body to realize the uniform distribution; sintering shaping is performed to obtain the compact titanium-based composite material. The distribution of the nanometer onion carbon in the titanium-based composite material prepared by the method is uniform; the impurity content is low; the complete form can be maintained in the base body, so that the composite material has excellent comprehensive mechanical property.

Description

technical field [0001] The invention relates to a nano-onion carbon-reinforced titanium-based composite material and a preparation method thereof, belonging to the technical field of metal-based composite materials. Background technique [0002] Titanium and titanium alloys are new metals that have emerged after steel and aluminum. They have the characteristics of low density, high strength, high and low temperature resistance, corrosion resistance, and good biocompatibility. These outstanding characteristics make titanium and titanium alloys ideal materials for aerospace, marine, petrochemical, biomedical and other industries. At the same time, titanium and titanium alloys also have major problems such as poor wear resistance and low hardness. New ideas and methods are urgently needed to further improve the comprehensive mechanical properties of titanium alloys and meet the requirements of various related industries. [0003] Nano-onion-like carbon is called onion carbon ...
