WebFriction remains low in the first two regimes, but jumps to values also found for bare Pt (111) surfaces upon graphene rupture. While graphene substantially enhances the load carrying capacity of the Pt substrate, the substrate’s intrinsic hardness and friction are recovered upon graphene rupture. KEYWORDS: Graphene friction nanoindentation Web9 nov. 2024 · Friction is a force that always opposes motion. The frictional forces are majorly affected by the texture of the surface of the objects that came in contact with each other and the amount of force exerted on them. Frictional Forces are classified into four different types, they are rolling, sliding, static and kinetic friction.
