Abstract
This paper discusses the characteristics and classifications of different type of protective coatings being used in oil and gas industry. After a brief review of the fundamental aspects of organic and powder coatings, this paper discusses the investigation being done on the tribological and mechanical properties of electroless Ni–P (EN-P) composite coatings. The study covers its fundamental aspects, mechanical properties, applications and future trends. EN-P coating have found wide applications in aerospace, automobile, electrical and chemical industries but in the field of oil and gas pipelines, very little research has been done. Since EN-P coatings possess splendid tribological properties, technological advancement demands further improvement in newer variants of EN-P coatings like Ni–W–P, Ni–Cu–P, Ni–P–SiC, Ni–P–TiO2 and so on to find the optimum coating solutions in the field of oil and gas pipelines and its variants against corrosion.
