▎ 摘　　要

NOVELTY - An object (200) is coated by preparing a suspension containing graphene nanoplatelets and ceramic material; and spraying the suspension onto the object using high velocity oxy-fuel (HVOF) spraying in which the suspension is introduced as a feedstock. USE - Coating of object (claimed). ADVANTAGE - Graphene nanoplatelets are able to survive the high temperatures of HVOF flame, even though the nanoplatelets are dispersed in a suspension before being injected into the flame. Graphene nanoplatelets reinforced coatings increase the wear-resistance of the coating. Increased flame power increases the survivability of the graphene nanoplatelets. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) wear-resistant object comprising wear-resistant coating (201) containing ceramic material and graphene nanoplatelets where coating has been applied to object (200) using coating process; (2) coating an object which involves preparing a suspension containing graphene nanoplatelets; and spraying the suspension onto the object using high velocity oxy-fuel spraying in which the suspension is introduced as a feedstock; and (3) wear-resistant object comprising wear-resistant coating containing graphene nanoplatelets where coating is applied by coating process. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the high velocity oxy-fuel (HVOF) apparatus for applying a coating to object.
