Ni–P alloy–carbon black composite films fabricated by electrodeposition

Abstract

NiP alloycarbon black (CB) composite films were fabricated by electroplating and their microstructures and properties were examined. The CB and phosphorus contents of the composite films were also investigated. The CB particles were found to be embedded in the NiP alloy matrix. The CB content in the deposits increased, reached a maximum value of 0.77 mass % with increasing CB concentration in the bath up to 10 g dm 3 , and then decreased with a further increase in the CB concentration in the bath.Both before and after heat treatment, the composite films had higher hardnesses and lower friction coefficients than the NiP alloy films. Both before and after heat treatment, the friction coefficient of 0.77 mass % CB composite films was about half that of NiP alloy films without CB.

Effect of Nano-TiC Dispersed Particles and Electro-Codeposition Parameters on Morphology and Structure of Hybrid Ni/TiC Nanocomposite Layers

“…The reason could be that the TiC nanoparticles are good conductors, and the resulting electric field is stronger around clusters than elsewhere due to increased current density. This observation has been reported by other authors but by using other composites such as Ni-carbon black (CB) and Ni-carbon nanotubes (CNT) [ 24 , 25 ].…”

Ni-P-TiO2 nanocomposite coatings with uniformly dispersed Ni3Ti intermetallics: effects of TiO2 nanoparticles concentration

“…As it can be clearly seen in Figure 6(a,d,g), the formed intermetallic are dispersed in uniform manner. Incorporation of Sodium dodecyl sulphate surfactant into the plating bath coupled with the application of ultrasonic vibration are responsible for this uniformity [30]. Nevertheless, Chou et al [13] have reported that the application of ultrasonic vibration prior to electrodeposition process is more efficient than introduction of the surfactants.…”
