Plating of Electrical Equipment
Published in Bella H. Chudnovsky, Transmission, Distribution, and Renewable Energy Generation Power Equipment, 2017
There are some special applications of nickel plating, such as for the aluminum used for electrical products such as wires, cables, or terminal connectors. In some industrial applications, the surface of the metal has to be modified in order to promote a good and durable electrical contact. This is particularly the case for the aerospace industry, where nickel electroplating on aluminum has proved to be a good means of significantly improving the surface conductivity of the substrate.

Depending on the second phase particles used as the reinforcement, a particular mechanical and/or physical or chemical property such as corrosion resistance, stiffness, hardness, internal stress, wear resistance and COF can be enhanced [2,3]. Suspended second phase particles in the electrolyte are carried and coated in tandem with nickel ions to cathode surface to form a nickel matrix composite structure during deposition. Organic materials are usually used as surfactants for the suspension of the second phase particles [2]. These additives dissolve in the solution and act as a wetting agent for the surface of the second phase particles. They regulate the zeta potential to provide suspension of the second phase particles in the electrolyte. In the case of nickel electroplating, it is known that dissolved nickel ions in the electrolyte are carried from anode to cathode where the reduction of positively charged nickel ions takes place. While moving to the cathode, nickel ions are adsorbed by the negatively charged second phase particles and carry them to cathode surface to form a MMC coating [4]. The addition of many second phase particles including AlN [5], MoS2 [6], TiO2 [7], Mo [8], graphite [8], TiO2-TiC [9], WC [10,11], CeO2 [12], diamond [13], W/diamond [14], graphene [15], Al2O3–TiO2 [16], Al2O3 [17,18], WS2 [19], B4C [20], La2O3 [21], SiC [22], SiC-W [23] and ZrO2 [24] to the nickel matrix have been studied previously to modify the surface properties.
