Abstract: A carbon coating such as graphene formed on an article or component forms a reduced friction surface on the component. The graphene forms a superlubricity coating for mitigating friction against engaged, moving surfaces. A metallic component receives a graphene coating resulting from a high temperature biowaste treatment (HTBT) by surrounding the metallic component with a granular biowaste medium defining a carbon source, and heating the metallic component in the biowaste medium for diffusing carbon from the biowaste medium to aggregate on a surface of the component, thereby forming a graphene coating.
