Definitions

  • Nickel because of its corrosion resistant properties, is used extensively in the form of plating to protect other and more vulnerable materials from atmospheric corrosion. For decorative purposes, nickel deposits are frequently used for corrosion resistance and the thin covering of chromium provides additional tarnish resistance. However, the decorative covering of chromium adds little to the protective value of the nickel plating when the customarily very thin chromium deposits are used.
  • the corrosion of the resultant nickel-chromium coating generally proceeds at pores in the coating. These pores may exist originally because of imperfections in the electroplating process; the coating may be too thin, or the pores may develop as a result of local corrosion of the metallic coating itself. In any event, the corrosion causes the basic metal to suffer accelerated galvanic corrosion at the base of the pore, because of its small anodic area and the large cathodic area of the protective coating.
