Improved friction and wear of grey cast iron by graphene at interfaces

What is it about?

Graphene coating is found to be an very efficient material in improving friction and wear of materials. Graphene coating has been successfully performed on the grey cast iron surface by CVD for the first time and friction and wear consequences have been studied due to graphene at the interfaces.

Why is it important?

The paper demonstrates the synthesis of few-to-multilayer graphene on grey cast iron (GCI) by chemical vapor deposition (CVD) method. It focuses on the study of the tribological behavior of graphene-coated GCI specimen and explains the possible mechanism at the interfaces in the reduction of friction and wear of material. Graphene synthesized on GCI by CVD has not been used for the study of its tribological behavior in the past to the best of our knowledge. So, the work shows its novelty as an investigation on the tribological behavior of graphene coated on GCI. We assume the study contributes to the efficient application of graphene to the tribological components considering the graphene coating on various machine parts and components. As such this paper provides interest to a broad readership including those interested in the synthesis of graphene on transition metals and alloys, as well as those studying in the application of graphene in the fields of surfaces, interfaces, and Tribology.
