▎ 摘  要

It is known that graphene is stronger than steel. It is characterized by extremely high values of the Young's modulus (up to 1 TPa), strength (similar to 125 GPa) and thermal conductivity (similar to 5000 W/(m center dot K)). Therefore, in this work it is used to obtain nano-bio composite materials aluminum-graphene using powder metallurgy methods, in particular high-energy ball grinding followed by vacuum sintering. Sintered composite materials were evaluated using modern methods of microstructure analysis, such as scanning electron microscopy with field emission (FE-SEM), energy dispersion spectroscopy (EDS), transmission electron microscopy (TEM) and Raman spectroscopy for qualitative and quantitative analysis of aluminum characteristics. According to the results of research, a homogeneous distribution of components is observed in the structure of the material over the given scan areas. The relative density of the composite after sintering is approximate to 97.5%. Data on the electrical conductivity of aluminum-graphene nano-structured bio-composite materials provide grounds for their use in bone engineering.
