Abstract
Systems and processes for forming seals. The seals have graphene embedded in the seal. The graphene-embedded seals exhibit improved wear resistance over seals without graphene.
Claims19
A method of forming a graphene-embedded seal comprising:
- mixing graphene and alcohol forming a graphene alcohol solution;
- and
- cold pressing polymer powder to form a pressed seal powder;
- exposing the pressed seal powder to the graphene alcohol solution wherein a portion of the graphene alcohol solution infiltrates the pressed seal powder forming an infiltrated pressed seal powder;
- and
- sintering the infiltrated pressed seal powder forming a polymer seal having graphene embedded within the polymer seal.
