Many engineering coatings on oilfield equipment are used to increase their lifespan by offering protection against wear and corrosion. Some of these coatings also serve the purpose of flow assurance by reducing downhole scale buildups during flow. The present paper investigates the ability of various engineering polymer coatings in reducing carbonate scale deposition under different environments (static and dynamic carbonate scaling under pressurized autoclaves). Graphene, as an additive to engineering thin polymer coatings, has been investigated along ceramic nano-additives to determine their potential tribological and anti-scaling contributions. In addition to scaling, all coatings were evaluated for their wear and frictional properties, including anti-galling performance and friction under variable loads. The paper establishes that graphene enhances hardness, wear resistance, without major changes in friction, galling, and carbonate scaling behavior. Some data suggest that graphene, in specific concentrations, may offer carbonate scaling reduction advantages. |
