Abstract

The invention relates to a method for producing and using graphene on polycrystalline silicon carbide. In order to provide a method for producing surfaces having very little friction, the invention includes the following method steps: polishing the surfaces of silicon carbide bodies with a homogeneous distribution of carbon; cleaning the silicon carbide bodies; and graphenizing at least one of the polished surfaces by means of an annealing treatment at temperatures from 1500 to 1700°C for 10 to 20 minutes in flowing argon. Within the scope of the invention, it has unexpectedly been found that it is possible on polished layers of solid phase-sintered silicon carbide to achieve surfaces that are characterised by a very low friction, which is attributable to the presence of graphene layers on the surfaces of silicon carbide grains of different orientation.
