The accelerating effect of galvanic corrosion in the far-interface region has been weakened, its corrosion behavior is similar to the self-corrosion behavior of carbon steel in the marine environment...

... than the Ni layer) and a polarization resistance of 513951 Ω·cm². Long-term immersion tests showed that the Ni/Bayerite-6h coating delayed corrosive medium penetration for up to five days and can still prevent galvanic corrosion between the nickel layer and the aluminum substrate after seven...
