Nickel Coating - an overview ScienceDirect Topics

Nickel coatings are not resistant to nitric acid and environments containing chloride. The life of nickel coatings may be further increased by a thin overlay of microcracked chromium because corrosion would not penetrate the nickel directly but spread laterally. Nickel
