▎ 摘　　要

NOVELTY - Preparing a graphene-reinforced titanium-based composite material by PE-CVD assisted SPS sintering comprises using a plasma enhanced chemical vapor deposition (PE-CVD) technique to grow graphene in situ on the surface of the spherical titanium powder to obtain a Gr/titanium composite powder. Then the Gr/titanium composite powder is mechanically ball milled under inert gas protection until flakes. Then the Gr/titanium composite sheet is uniformly laid in a steel mold for low-temperature rapid discharge plasma sintering (SPS) to obtain a graphene-reinforced titanium-based composite material. USE - Method for preparing a graphene-reinforced titanium-based composite material by PE-CVD assisted SPS sintering. ADVANTAGE - The method enables to prepare a graphene-reinforced titanium-based composite material by PE-CVD assisted SPS sintering, which has uniform dispersion, strong interface bonding and excellent comprehensive mechanical properties.
