Abstract
A system and method for forming at least one of graphene and graphene oxide on a substrate and an opposed wear member. The system includes graphene and graphene oxide formed by an exfoliation process or solution processing method to dispose graphene and/or graphene oxide onto a substrate. The system further includes an opposing wear member disposed on another substrate and a gas atmosphere of an inert gas like N2, ambient, a humid atmosphere and a water solution.
Claims14
A method of interacting with reduced friction comprising:
- providing relative movement between a first surface having disposed thereon graphene oxide flakes and being substantially free of oil with a second surface having a diamond like coating;
- and
- interacting the first surface with the second surface wherein the coefficient of friction is between 0.15 and 1.0.
A method of forming graphene oxide on a substrate, comprising the steps of:
- disposing graphene oxide on the substrate substantially free of oil, thereby establishing a low friction wear surface;
- providing an opposing wear member comprising diamond like coating (DLC);
- and
- positioning the low friction wear surface and the opposing wear member in water wherein the opposing wear member slides against the graphene oxide on the substrate.
