Abstract

Black nickel deposits are produced from baths containing nickel, zinc and thiocyanate. The deposits obtained at low c. d. appear grey and those obtained at high c. d. exhibit vivid colours reminiscent of interference colours and appear black in thick layers. The former is found to be rich in Nickel and the latter is zinc rich. A theoretical explanation for the colour of black nickel is proposed. The role of electrochemical factors in the production of deposits displaying colours is explained.
