▎ 摘  要

The frictional anisotropy of metallic nanoparticles is investigated using a molecular dynamics method. Calculations of anisotropy have been performed for aluminum, palladium, and platinum nanoparticles containing 10,000 atoms. Anisotropy is studied at high sliding velocities of nanoparticles over the graphene surface. The influences of incommensurability and short-range order of nanoparticles' contact surfaces lead to the absence of pronounced angular dependence of frictional force.
