Beschreibung
Zusammenfassung:	A multifunctional coating method involves cleaning a surface, applying a layer of corrosion-resistant alloy coating to the surface, and applying an oleo-hydrophobic composite coating over the corrosion-resistant alloy coating. An oil and gas pipe has an inner surface with a multifunctional coating applied using the multifunctional coating method, and has an inner oleo- hydrophobic composite coating, beneath the inner oleo-hydrophobic composite coating a corrosion-resistant alloy coating, and beneath the corrosion-resistant alloy coating untreated pipe or any other metallic substrate. Procédé de revêtement multifonctionnel comprenant le nettoyage d'une surface, l'application d'une couche de revêtement d'alliage résistant à la corrosion sur la surface, et l'application d'un revêtement composite oléo-hydrophobe sur le revêtement d'alliage résistant à la corrosion. Un tuyau d'huile et de gaz a une surface interne avec un revêtement multifonctionnel appliqué à l'aide du procédé de revêtement multifonctionnel, et a un revêtement composite oléo-hydrophobe interne, sous le revêtement composite oléo-hydrophobe interne, un revêtement d'alliage résistant à la corrosion, et sous le tuyau non traité de revêtement d'alliage résistant à la corrosion ou tout autre substrat métallique.
