▎ 摘　　要

NOVELTY - Preparation method of core-shell net-shaped titanium base composite material involves mixing and sintering the titanium-based material and high-purity graphite spheres to obtain a graphene-interface core-shell network titanium-based composite material, where the powder mixing process comprises graphene adding stage and uniform mixing stage. The ball milling of high-purity graphite balls and matrix powder is carried out in the graphene addition stage, where the ball milling frequency is 10-300r/min. The carbon source is taken out, after the ball milling. The hard grinding balls are added for ball milling in the uniform mixing stage where the frequency of ball milling is 10-150r/min, and the milling time is 30-300min. USE - Preparation method of graphene-interface phase core-shell network titanium matrix composite material used in aircraft engine. ADVANTAGE - The composite powder preparation process of titanium-based composite materials does not need to add any process control agent and only needs to add a required amount of graphene and add hard grinding balls to disperse evenly before sintering, thus realizing the economical and efficient preparation of composite materials. Hence, the preparation process is green and pollution-free. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical representation of the laser Raman spectrum of graphene coated on the powder particles. (Drawing includes non-English language text).
