â¢Effect of graphene as lubricant additive in grease has been investigated.â¢Performance of new lubricant compound evaluated on real mechanical component.â¢Dedicated test rig developed for experimental tests.â¢CoF evaluated in different component working conditions.
Improving machine efficiency and reliability is an endless challenge that is even more important considering environmental issues related to fuel consumption and the related emissions. One way to reduce machine losses is to reduce components friction. In this paper, the effect graphene added to standard grease to create a high performance lubricant has been investigated. Experimental tests have been performed on a mechanical component (a spline coupling) commonly used in many industrial applications. In particular, the friction force has been measured lubricating the parts with different compositions of grease-graphene compounds. Tests have been performed by means of a dedicated test rig. Results show that graphene added to grease reduces the coefficient of friction.
