▎ 摘　　要

NOVELTY - Cathodic protection system (S1) (100) comprises: a vessel (102) for containing a fluid; an anode positioned inside the vessel; a hydrophilic and oleophobic coating covering at least a portion of the anode, where the coating allows ions to pass therethrough and repels oil and wax contaminants from reaching at least a portion of the anode; and an impressed current source electrically connected to the anode and the vessel, where the vessel is a cathode when current is applied from the current source and the coating has a thickness of 10-900 mu. The coating comprises: a single layer having graphene oxide; a conductive filler material and an oleophobic binder; particulate conductive functional additives and an oleophobic binder; a composition made of a metal and a non-metallic organic or inorganic material and an oleophobic binder; and two distinct layers including a first conductive layer in contact with the anode, and a second oleophobic layer positioned over the first layer. USE - The systems are useful for providing corrosion protection to a vessel (claimed) and protecting metallic structures from corrosion. ADVANTAGE - The systems: utilize coating includes a composition that has both conductive and oleophobic properties; utilize coating that has a thickness of 10-99 mu; and protect sufficient corrosion protection inside the vessel that is ensured by the dimensionally stable impressed current anode with oleophobic or hydrophilic coating in cases in which galvanic sacrificial anodes might be completely depleted during operation. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (a) providing corrosion protection to a vessel; and (b) a cathodic protection system (S2). DESCRIPTION OF DRAWING(S) - The figure shows cross-sectional view of an impressed current cathodic protection system.
