An assembly for a vehicle having reduced galvanic corrosion includes a first component defining at least one interface region that includes a carbon-fiber reinforced polymeric composite (CFRP) and a first material present in the at least one interface region and having a first electrochemical potential. A second component has a second material and is in contact with the at least one interface region of the first component. The second material has a second electrochemical potential different than the first electrochemical potential. In this manner, in the presence of an electrolyte the first material may be either less noble than the second material and serve as a sacrificial material or alternatively more noble to the second material reducing a driving force for corrosion. Methods of reducing galvanic corrosion in an assembly (e.g., for a vehicle) are also provided.

A passive cathodic protection process for preservation of em bedded metallic foundations entails embedding a wrap around a metallic foundation. The wrap has an outer sheath and an inner absorbent mat to be in direct contact with the metallic foundation. The is also mat hydrophobic. The wrap is subsumed such that an upper edge of the wrap is accessible. An oil-based metallic soap is injected via the upper edge to impregnate the mat. The metallic soap is selected from a set of metallic soaps such that the metal of the metallic soap is more electropositive than the metal of the metallic foundation such that the metallic soap acts as an anodic solution for galvanic exchange with metal within the em bedded metallic foundation for the passive cathodic protection thereof. For example, zinc naphthenate may be selected for steel or aluminium foundations thereby allowing for both passive cathodic protection and biocidal action.

A metal (carbon steel) tank receives growth media containing an electrolyte. An anode is positioned within the growth media in electrical contact with the metal tank to polarize the anode and the metal tank with a potential difference therebetween. The metal tank becomes a cathode when a potential difference is established between the metal tank and the anode. The anode, the cathode, and the electrolyte form an electrochemical cell. The carbon steel tank will be protected for twenty to thirty years.
