production, was coated on the aluminum surface to increase the
corrosion resistance. The polymer composite coated metal has high
contact resistance because the composite has a polymer-rich layer
on both sides of the surface [6]. In an effort to decrease the contact
resistance, carbon black particles and carbon paper were added to
make an interfacial layer between the metal and composite coating
layer. The effects of the interfacial layer on the contact resistance
and corrosion behavior were examined.
