Reduced wear and friction enabled by graphene …

2013-8-1 · We report on the friction and wear behavior of graphene-lubricated 440C steel test pairs in dry nitrogen under different loads. Tribological test results have revealed that a few-layer graphene is able to drastically reduce the wear and the coefficient of friction (COF) of 440C steel during the initial sliding regime and under low load conditions.

Sliding Friction » The Physics Crew

Friction is a force that opposes the motion of any object. The frictional force acts on sliding as well as rolling bodies or bodies are at rest. The resistance from the static friction causes a body to roll. Definition of Sliding friction: Sliding friction can be defined as the resistance offered by any two objects when they are sliding against each other.
