Electrolytic nickel plating. Specifications

For nickel-cobalt, nickel-iron or nickel-molybdenum deposits, we refer the reader to Louis LACOURCELLE's treatise on galvanotechnics [5] . These codeposited alloys are used for different purposes: obtaining brilliant deposits, the economic interest of replacing nickel by iron, resistance to chemical agents in the case of Ni-Mo (20 to 30% molybdenum).

In response to increasing pollution control requirements for processes using hexavalent chromium, a number of alloy deposition processes have been developed, particularly nickel-based (but also cobalt-based). In the case of nickel, Ni-Sn and Ni-W alloys have been developed, although their use is still limited (see
