The Alumina-Al-graphene composite coatings exhibited impressive mechanical properties, including high hardness (913 GPa), elastic modulus (100150 GPa), and toughness (213 MPam 0.5) along with exceptional adhesion (35 MPa).
The amount of graphene will determine the optimum mechanical properties of the Al-graphene composite rather than the type of graphene structure. The incorporation of graphene in a small amount will strengthen the composite, whereas the addition of more graphene weakens them. The maximum strengthening efficiency is determined by graphene dispersion.
