Abstract

The invention discloses a nano-diamond reinforced titanium-based composite material as well as a preparation method and application thereof. The composite material is mainly made from nano-diamonds and matrix titanium, wherein the nano-diamonds are used as reinforcing phases, and are uniformly dispersed in a matrix of metallic titanium to play a dispersion strengthening role. The invention also discloses a preparation method and application of the nano-diamond reinforced titanium-based composite material. In comparison with the prior art, by using the nano-diamond reinforced titanium-based composite material as well as the preparation method and the application thereof, the defects that an existing pure titanium material is poor in mechanical properties and a carbon nano tube or a graphene reinforced titanium-based composite material is high in cytotoxicity are overcome; and the obtained nano-diamond reinforced titanium-based composite material has higher hardness, strength and plasticity and favorable biocompatibility. A product of the nano-diamond reinforced titanium-based composite material can be applied to the field of biomedicine, and particularly to the repair and the substitution of hard tissue of a department of orthopedics, a department of dentistry, and the like.
