A protective cover system ( 100 ) for inhibiting corrosion of a metallic object. The protective cover system includes a cover ( 101, 200, 600 ) for defining a microenvironment and a corrosion inhibitor source for releasing one or more corrosion inhibitors into the microenvironment. In one embodiment, cover 200 comprises an outer liquid-impermeable layer ( 204 ), an inner liquid-permeable layer ( 202 ), and a superabsorbent layer ( 206 ) located between the outer and inner layers. In another embodiment, cover 600 includes a water-vapor-permeable layer ( 602 ) and a porous support layer ( 606 ) for supporting the water-vapor-permeable layer. In both of these embodiments, one or more corrosion inhibitors may be incorporated into the cover in one or more of the corresponding above-mentioned layers or in a layer separate from these layers, or may be provided in a separate container that fluidly communicates the corrosion inhibitor(s) to the microenvironment. |
