  This article is a continuation of our previous studies of the frictional
anisotropy of metal nanoparticles on the surface of a graphene substrate for
other temperature conditions. The friction force acting on palladium
nanoparticles on a graphene sheet in various lateral directions is investigated
using classical molecular dynamics modelling. Anisotropy is studied at high
sliding speeds of nanoparticles consisting of 10000 atoms on the surface of
graphene. The effect of incommensurability and short-range order of the contact
surfaces of nanoparticles, as well as the graphene deformation lead to the
absence of an expressed angular dependence of the friction force.
