| Abstract Scope |
Several engineering coatings applied to energy-producing equipment aim to extend their lifespan by protecting them from wear and corrosion. Some of these coatings play an important role in flow assurance by minimizing mineral scale accumulation during operation. Our previous research has demonstrated the efficacy of various polymeric and thin carbon-based coatings in mitigating mineral scale buildup. The surface roughness or finish of oil field components holds significant implications for both manufacturing costs and the effectiveness of coating applications. This study examines how varying surface roughness (across seven different finishes) affects the deposition and adhesion of mineral scale on both coated and uncoated diamond-like carbon (DLC) surfaces. The surface roughness impact on wear and frictional characteristics of the coating. The study determines and discusses the threshold limit of coating surface finish required for scale prevention, based on surface energy, contact angle data, mass gain, and scale adhesion strength. |
