Abstract
Official abstract text for this publication.
A solid-state lubricant composition is disclosed. The solid-lubricant contains graphene, an oxide of a metal, and one or more polymeric binders. A method of making a solid-state lubricant coating on various substrates is disclosed. The method includes the steps of making a homogeneous slurry comprising powder of an oxide of a metal, graphene, and a polymeric binder with organic volatile solvent; coating a substrate with the homogeneous slurry with desired thicknesses; and drying the slurry on the substrate naturally or applying additional heat, resulting in a solid lubricant coating on the substrate. Substrates with coated solid composite lubricant show wear reduction and lower coefficient of friction compared with uncoated substrates.
First claim
Opening claim text (preview).
The invention claimed is: 1. A solid-state lubricant composition comprising: graphene, an oxide of a metal, and a polymeric binder, wherein the weight percent of graphene is in the range of 80 to 85. 2. The solid-state lubricant of claim 1 , wherein the metal is one of zinc, tin, molybdenum, silver, copper, lead, indium and antimony. 3. The solid-state lubricant of claim 2 , wherein the metal is zinc. 4. The solid-state lubricant of claim 3 , wherein the weight percent of the oxide of zinc is in the range of 5 to 20. 5. The solid-state lubricant of claim 4 , wherein the weight percent of the oxide of zinc is in the range of 10 to 15. 6. The solid-state lubricant of claim 1 , wherein the weight percent of the polymeric binder is in the range of 2 to 10. 7. The solid-state lubricant of claim 6 , wherein the weight percent of the polymeric binder is in the range of 5 to 8. 8. Solid-state lubricant of claim 1 , wherein the polymeric binder is one of polyvinylidene difluoride, polyethylene oxide, polyvinyl acetate, and polytetrafluoroethylene.
