▎ 摘  要

NOVELTY - Carbon nanotube and graphene synergistically reinforced alumina-based composition material comprises 10-40 mass% titanium carbide, 0.1-2 mass% calcium oxide, 0.1-2 mass% yttrium oxide, 0.1-5 mass% graphene treated with surface modification, 0.1-5 mass% carbon nanotube treated with surface modification, and up to 100 mass% alumina. USE - Used as carbon nanotube and graphene synergistically reinforced alumina-based composition material. ADVANTAGE - The material has uniform and compact structure, low porosity and high density, thus exhibiting excellent mechanical properties and the method does not produce pollutants e.g. waste gas and waste residue, and has a simple process and is easy to produce. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the material comprising weighing each component, and then combining each component ball milling and mixing are performed to obtain composition powder, then, the subjecting composition powder to spark plasma sintering to obtain the material.
