Abstract
A sliding component may include an overlay. The overlay may include graphene platelets functionalised with at least one of —O functional groups and —F functional groups within a matrix of at least one of a polymeric material and a plastics material.
Claims20
A sliding component comprising an overlay including graphene platelets functionalised with at least one of —O functional groups and —F functional groups within a matrix of at least one of a polymeric material and a plastics material.
An overlay material comprising a matrix of polymeric material, and, within the matrix, graphene platelets functionalised with at least one of —O functional groups and —F functional groups.
A graphene platelet filler for an overlay material, comprising graphene platelets functionalised with at least one of —O functional groups and —F functional groups.
A method of forming an overlay for a sliding component, comprising:
- forming a dispersion via mixing a polymeric material with graphene platelets functionalised with at least one of —O functional groups and —F functional groups;
- and
- depositing the dispersion onto a substrate.
An engine comprising a sliding component including an overlay having a matrix of at least one of a polymeric material and a plastics material, the overlay including functionalised graphene platelets dispersed within the matrix, wherein the functionalised graphene platelets are functionalised with at least one of —O functional groups and —F functional groups.
