“…The hardness of the deposits was mainly associated with the grain size, similar to a previous study on electrodeposited Cu with gelatin [10]. However, a dominant (111) texture [26] with lower porosity and fewer impurities [19] also leads to higher hardness. Overall, the reduction in hardness could be ascribed to an increase in the grain size, even though this was controlled.…”

“…Figure 7 presents the XRD patterns of deposits electrodeposited after 20 min and the respective texture coefficient TC [19]. It shows that DCE-processed Cu had a preferential (111) orientation that is consistent with the tendency of the (111) texture to appear at high current densities [26].…”

“…It has been reported that the quality of the deposit can be improved by introducing physical friction to the electrodeposition process. Lv et al [19] reported grain refinement and a dense deposit in Ni electrodeposited with the use of flexible friction. Zhu et al [20] developed a hard particle friction electrodeposition technique by adding hard particles when polishing the cathode surface, leading to dehydrogenation and NC Ni with a smooth surface.…”

Ultrafine-grained (UFG) Cu deposits were prepared using pulse electrodeposition assisted by hard particle friction under strong cathodic polarisation in an additive-free bath. The effects of hard particle friction on the resulting electrochemical behaviour, microstructure, and mechanical properties of the deposits were studied. The results demonstrate that friction can effectively weaken the concentration polarisation and maintain the stability of the cathodic polarisation process. Periodic growth inhibition and the promotion of lateral growth owing to the applied friction lead to the formation of finer equiaxed grains (130 ± 5 nm). The UFG Cu deposits produced using friction-assisted pulse electrodeposition had a preferential (111) orientation, compared to a (220) orientation in deposits produced using conventional pulse electrodeposition. The corresponding tensile strength was 630 ± 15 MPa and the elongation to failure was 14.5 ± 2.5%. The hardness and surface roughness were 183-204 HV and Ra 46 ± 5 nm, respectively.

“…The electrolyte bath for Ni coating is prepared as per Watts bath standard with the following composition: nickel sulphate (NiSO 4 ) 250 g/L; nickel chloride (NiCl 2) 45 g/L; and boric acid (H 3 BO 3 ) 30 g/L [15][16][17][18][19][20][21][22][23]. The bath is prepared for 1 lit each for every sample in order to maintain the quality and homogeneity of the coating.…”

The present work concentrates on the nanocomposite coating on the mild steel substrate. The mild steel substrate demands good surface preparation in order to have better adhesive strength of coating. In the light of this, surface is grinded and cleaned later followed by rinsing. In this work, Ni-Al 2 O 3 composite coating was successfully coated on mild steel (AISI 1018) substrate. The study on different wear parameters on the specific wear rate is carried on. The experimental design is carried out with 20 trails as per central composite design considering normal load, sliding speed and sliding distance on the samples. The morphology of surface after coating and wear analysis is studied. The results revealed higher wear resistance by the presence of nano-Al 2 O 3 particles in the Ni matrix composite coating. The effect of normal load and its interaction with sliding distance are found to be more effective on specific wear rate. The abrasive nature of wear is observed due to the presence of hard Al 2 O 3 nanoparticles embedded in the Ni matrix. The chemical composition and distribution of particle analysis is carried out by SEM and EDS micrograph.

“…Nickel belongs to a group of metals allowing the formation of fine crystalline adhesive coatings [32][33][34]. Commonly used electrolyte for the electrodeposition of nickel coatings is a mixture of nickel sulfate and nickel chloride with the addition of boric acid as a buffer additive (Watts electrolyte) [35,36]. The solution is operated at elevated temperature (50-55 ºС), otherwise, it is impossible to achieve current efficiency close to 100% during deposition.…”

In this study, nanocrystalline Ni and Ni-diamond coatings were obtained by electrodeposition from tartrate electrolyte at ambient temperature to achieve good corrosion and wear resistance. Microhardness and adhesion tests respectively were performed for the wear resistance determination. Electrochemical impedance spectroscopy and linear polarization methods were used for corrosion resistance measurements and atomic force microscopy, and scanning electron microscopy were used for surface property characterization. The introduction of nanodiamond particles into the coating led to a rougher surface structure and a larger grain size in comparison with bare nickel coating. The study shows that the addition of 5•10 -2 (g•dm −3 ) of nanodiamonds to the plating bath is enough to obtain composite coatings with a clear increase in microhardness and wear resistance. The slightly improved corrosion resistance of the coating and decrease in corrosion current density from 0.41 to 0.14 μA•cm −2 in neutral chloride-containing medium, and nobler values of the corrosion potential were also observed.
