Wang et al. have shown that Ni/Cu bilayer coatings on a mild steel surface promote improved load-carrying capacity and reduced wear at up to 1 GPa contact pressures, but operate at elevated levels of friction. Myshkin and coauthors found that an electroless nickel-phosphorous (Ni-P) coating on copper tokens reduces both friction and wear under ~0.9 GPa contact pressures; the increased phosphorous content enabled the amorphisation of the nickel structure to reduce coating hardness and improve friction reduction. Luo et al. investigated the performance of a Ni/Cu/Ni trilayer coating on Ti-6Al-4V, which can reduce the wear of the alloy by ~60% (at 0.75 GPa Hertzian contact pressures), by promoting lubrication and reinforcement mechanisms of the coating. Further reductions were seen by annealing the coating, generating Ni-Cu and Ni-Ti diffusion layers that further reinforce the coatings from sliding wear. However, more information is needed to fully understand the influences on the tribological properties of such nickel-reinforced copper coatings.
