Protective Cover System Including a Corrosion Inhibitor and Method of Inhibiting Corrosion of a Metallic Object

Abstract

A protective cover system for inhibiting corrosion of a metallic object. The protective cover system includes a cover for defining a microenvironment adjacent a metallic object and a corrosion inhibitor source for releasing one or more corrosion inhibitors into the microenvironment.

1 . A protective cover for a metallic object, comprising:
 a first layer having a first face and a second face, said first layer comprising a superabsorbent material adapted to absorb and store moisture;   a second layer, confronting said first face of said first layer, comprising a non-porous water vapor permeable film; and   a third layer, confronting said second face of said first layer, comprising liquid permeable material.   
     
     
         2 . The protective cover of  claim 1 , further including a fourth layer continuously secured to said second layer opposite said first layer, said fourth layer being a porous layer having passageways extending through said fourth layer. 
     
     
         3 . The protective cover of  claim 1 , wherein the protective cover is for defining a microenvironment adjacent a metallic object during use, the protective cover further comprising a vapor corrosion inhibitor source for providing at least one vapor corrosion inhibitor to the microenvironment during use of the protective cover. 
     
     
         4 . A panelized cover system for protecting an object from moisture, comprising:
 a plurality of panels each comprising:
 a first layer having a first face and a second face, said first layer comprising a superabsorbent material adapted to absorb and store the moisture; and 
 a second layer located adjacent said first face of said first layer, said second layer being liquid-impermeable; 
   wherein each of said plurality of panels is fastened to at least one adjacent one of said plurality of panels.   
     
     
         5 . The panelized cover system of  claim 4 , wherein each of said plurality of panels further comprises a vapor corrosion inhibitor source. 
     
     
         6 . The panelized cover system of  claim 4 , wherein adjacent ones of said plurality of panels are fastened to one another with a refastenable fastener. 
     
     
         7 . A panelized cover system for protecting an object by forming a microenvironment adjacent the object when the panelized cover system is applied to the object, comprising:
 a plurality of panels each comprising:
 a first layer having a first face and a second face and comprising a liquid-impermeable water-vapor-permeable material; and 
 a second layer continuously attached to said first layer at said first face of said first layer and being made of a porous material; and 
   a corrosion inhibitor source for providing at least one corrosion inhibitor to the microenvironment when the panelized cover system is applied to the object;   wherein each of said plurality of panels is fastened to at least one adjacent one of said plurality of panels.   
     
     
         8 . The panelized cover system of  claim 7 , wherein said corrosion inhibitor source is incorporated into ones of said plurality of panels. 
     
     
         9 . The panelized cover system of  claim 7 , wherein adjacent ones of said plurality of panels are fastened to one another with a refastenable fastener.
