Abstract

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.
