The electrodeposition of nickel–graphite composite layers

By control of the deposition conditions, it is shown that it is possible to fabricate Ni/graphite composites where the surface is made up of isolated, single graphite particles uniformly dispersed across the nickel layer. In addition to other parameters in the preparation of inclusion deposits, it is shown that the mass transport regime in the electroplating bath strongly influences the graphite loading. In addition, it is confirmed that a uniform mass transport regime is essential to the achievement of a uniform distribution of particles over the entire coated surface.

Research highlights
► Nickel composites with an isolated, single 2 μm graphite particles can be achieved.
► Mass transport regime is a critical parameter.
► Uniform deposits of isolated graphite particles in a Ni surface are possible.
