| Abstract Scope |
Engineering coatings used on oilfield equipment are designed to extend service life by providing protection against wear and corrosion. In addition, certain coatings contribute to flow assurance by minimizing downhole scale buildup during fluid transport. This study investigates graphene nanoparticle-reinforced polyether ether ketone (PEEK)-based coatings for enhanced tribological and anti-scaling performance. Graphene was incorporated as a nano-additive in concentrations ranging from 0.5 to 2 wt% into PEEK coating using a conventional spray-and-bake process with additional nano-scale additives. The coatings were evaluated for wear resistance, friction coefficient, anti-galling behavior, and frictional response under variable loading conditions. Non-stick characteristics were assessed using water contact angle measurements, while anti-scaling behavior against carbonate scale deposition was also investigated. The performance of graphene-reinforced PEEK coatings was compared with previously studied graphene-reinforced polyphenylene sulfide (PPS)-based composite coatings. The results demonstrate that the incorporation of graphene, together with other nano-additives, improves the frictional behavior and wear resistance. |
