Abstract

When electrodeposition of nickel is used for corrosion protection of steel two aspects are important: the porosity of the coating and the resistance against corrosion provided by the coating itself. Using simple pulsed current (PC) plating, the size of the deposited crystals can be significantly smaller, thereby reducing porosity correspondingly. This usually also leads to improved hardness of the coating. Introducing pulse reversal (PR) plating, the most active crystals are continuously dissolved during the anodic pulse, providing a coating with improved subsequent corrosion resistance in almost any corrosive environment. This correlation between film texture and corrosion resistance will be discussed.
