▎ 摘　　要

NOVELTY - Preparing graphene-reinforced titanium-based composite materials by microwave sintering comprises (i) non-sensitizing and non-activating copper plating on graphene, (ii) uniformly compounding the copper-plated graphene and titanium alloy powder obtained in step (i) using electrostatic self-assembly combined with ultrasonic assisted stirring process, (iii) adding the mixed liquid of copper-plated graphene and titanium alloy powder obtained in step (ii) into ball milling tank for ball milling, (iv) compressing the powder obtained by drying the ball-milled mixed liquid in step (iii) into blank, and (v) placing the blank in microwave sintering furnace for sintering to obtain graphene-reinforced titanium-based composite material. USE - The preparing graphene-reinforced titanium-based composite materials by microwave sintering. ADVANTAGE - The method has simple process and high repeatability. The graphene has high degree of dispersion in the titanium matrix, and microwave low-temperature rapid sintering accelerates density of the block, inhibits and reduces formation of titanium carbide phase. The composite material has high density, good strength and toughness.
