“…The decorated particles are usually used for producing the metal/particle composition by the co-deposition approach, which has been widely used in the field of material modification. − Celis et al found that the particles were first surrounded by ionic clouds and then driven by the electrophoresis force toward the cathode surface, adsorbed on it, and finally buried by the metal atoms produced by electrodeposition. In later decades, researchers found that the ionic clouds around the particles can be achieved by decorating surfactants on the surface of the particles. − Kılıç et al used a cation surfactant, named, CTAB, to decorate the surface of the SiC particles.…”

Cetyltrimethyl ammonium bromide (CTAB) is used to decorate the SiC particle surface. The mechanism of the decoration process has been studied by simulation and experimental approaches. Molecular dynamics (MD) simulation finds a bilayer adsorbed structure of CTAB on the SiC particles, which is then verified by Fourier-transform infrared and thermal gravimetric analysis measurements. The MD simulation also finds that the decorative effects of CTAB on the SiC particle surface are related to the surface charge condition of the SiC particles and the concentration of CTAB. The measured zeta potential of the SiC particles shows dependence on the pH condition and the concentration of CTAB. The decorated SiC particles are used to produce composition by the co-deposition technology. With the help of CTAB, SiC particles are successfully incorporated in the deposited layer, where the content of SiC particles is dependent on the concentration of CTAB and the pH of the bath.

“…In addition, a significant finding concluded the improvement of wear resistance obtained from the coating of Ni-CeO 2 nanoparticles onto the surface of anodic titanium oxide (ATO) surface with nanoporous structure [6]. The paper [7] presents the result of the effectiveness of electrodeposition of nanocrystalline Ni-WO 3 . The two major sources of Ni and WO 3 including Ni(SO 3 NH 2 )2•4H 2 O and Na 2 WO 4 •2H 2 O respectively were applied.…”

An experimental investigation on synthesis of nanocrystalline nickels by pulsed current electrodeposition has been carried out in an additive-free Watts bath employing nickel-sulphate solution with similar nickel ion concentrations. Aluminum was used as a substrate. It demonstrated the advantage of easier removal process of electrodeposited nanocrystalline nickel from its substrate. Whereas the use of high-purity nickel anode was intended to replace nickel ions, which decreased during electrodeposition. Different peak current densities of 450, 750 and 1000 mA/cm2 were applied. A pulsed current was set at a similar pulse pattern of on-time and off-time of 1 ms and 9 ms respectively. The shorter on-time demonstrated the ability to limit ion deposition, which was related to the formation of finer grains. The off-time arrangement was targeted to ensure that the ion mobility had completely stopped. Higher current density demonstrated a dominant impact on deposits, generating a higher nucleation rate that is related to depositing nanocrystalline nickel. A peak current density of 1000 mA/cm2 produced grain sizes in the nanoscale regime. Without any additional additive, nanocrystalline nickel was successfully yielded. Investigation of grain size obtained from the 1000 mA/cm2 has been conducted by extracting full width at half maximum peak intensity (FWHM) revealed from X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM) exhibited consistent results of 22 nm and 25.4±3.4 nm, respectively. It is also evidence of the significant role of pulsed current density. In inclusion, nanocrystalline nickel can be synthesized in an electrodeposition bath without any addition of additives

Strengthening mechanisms and wear behavior of electrodeposited Ni–SiC nanocomposite coatings

The present paper describes the study of the synergism between the matrix microstructure and reinforcement phase in electrodeposited nanocomposite coatings. Adding hard nanoparticles into the metallic matrix leads to hardening of the coating. The effects of particle load, size and dispersion on hardening as well as their influence on metal microstructure refinement were studied. The relative contributions of strengthening factors in Ni/nano-SiC composites, namely, Hall–Petch strengthening, Orowan strengthening, enhanced dislocation density and particles incorporation, were evaluated. The production of various coatings under different stirring conditions and powders resulted in dissimilarities in the incorporation of particles. The Hall–Petch relationship for pure nickel was determined using samples produced under different current densities. Additionally, the grain refinement resulting from the particle codeposition and agitation mode were identified as influential factors in grain-size strengthening. Dislocation density strengthening was significant in electrodeposits produced using ultrasonic agitation, while it was negligible in layers produced under other conditions. Particles codeposition affected the magnitude of Orowan strengthening, resulting in cases where strengthening was negligible despite the presence of particles. The sum of contributions and the modified Clyne methods were used to calculate the hardness of the composites based on the contribution of each strengthening factor, and the calculation results were in good agreement with experimental data. The wear behavior of the composites was analyzed by pin-on-disk measurements, and the results correlated with the strengthening mechanisms. Particle size, dispersion and content increased the strengthening effects as well as the hardness and wear resistance of the coatings. Graphical abstract
