▎ 摘  要

NOVELTY - Preparing graphene-reinforced titanium-based complex material comprises adding graphene nanosheets into absolute ethanol and ultrasonically dispersing in absolute ethanol, adding polyvinyl alcohol in spherical titanium alloy powder for milling, adding the mixed powder to the graphene nanosheet ultrasonic dispersion, adding the dispersed graphene-titanium alloy mixed powder for ball milling, carrying out pyrolysis reaction, rapidly solidifying the mixed powder, carrying out high pressure low temperature sintering and incubating. USE - The method is useful for preparing graphene-reinforced titanium-based complex material (claimed). ADVANTAGE - The material has high dispersibility and high density; and can effectively inhibit the formation of titanium carbide. DETAILED DESCRIPTION - Preparing graphene-reinforced titanium-based complex material comprises (a) adding 5-20 g graphene nanosheets into 500 ml absolute ethanol and ultrasonically dispersing in absolute ethanol, (b) adding 4% polyvinyl alcohol in 1000 g spherical titanium alloy powder for milling, adding the mixed powder to the graphene nanosheet ultrasonic dispersion, (c) adding the dispersed graphene-titanium alloy mixed powder for ball milling, where the ratio of grinding media to material is 4:1 and carrying out pyrolysis reaction at 500 degrees C, (d) placing the mixed powder in a graphite mold coated with graphite paper, placing the graphite mold in a plasma sintering system, rapidly solidifying the mixed powder and vacuumizing the plasma sintering system, (e) placing the pressed blank in a stainless steel sheath, placing the stainless steel sheath into a hot isostatic pressing system, carrying out high pressure low temperature sintering and incubating, (f) cooling the sample sintering furnace and taking out the sample.
