“…This rapid change in the pulsing process leads to the formation of thin film by enhanced nucleation rate and limited growth rate resulting in a dense Si film as seen in Figure 2e,f similar to pulse electrodeposition of silver alloys [51]. A similar change in morphology has been reported for Sn thin films with the change in frequency of deposition wherein the morphology of Sn thin films change from porous large non-uniform grains to dense structures by increasing the pulse frequency [32].…”

“…In this regard, pulse electrodeposition is a well-known modification of traditional electrodeposition process and has been studied for varying the morphology, mechanical properties and composition of different types of metallic, composite, and nano coatings [32][33][34][35]. The pulse power electrodeposition approach offers an economical and easy way to change the grain size and morphology of the deposits, thus enhancing the density of coatings and their mechanical strength and corrosion properties [36][37][38][39].…”

Electrodeposition of amorphous silicon thin films on Cu substrate from organic ionic electrolyte using pulsed electrodeposition conditions has been studied. Scanning electron microscopy analysis shows a drastic change in the morphology of these electrodeposited silicon thin films at different frequencies of 0, 500, 1000, and 5000 Hz studied due to the change in nucleation and the growth mechanisms. These electrodeposited films, when tested in a lithium ion battery configuration, showed improvement in stability and performance with an increase in pulse current frequency during deposition. XPS analysis showed variation in the content of Si and oxygen with the change in frequency of deposition and with the change in depth of these thin films. The presence of oxygen largely due to electrolyte decomposition during Si electrodeposition and the structural instability of these films during the first discharge-charge cycle are the primary reasons contributing to the first cycle irreversible (FIR) loss observed in the pulse electrodeposited Si-O-C thin films. Nevertheless, the silicon thin films electrodeposited at a pulse current frequency of 5000 Hz show a stable capacity of~805 mAh·g −1 with a fade in capacity of~0.056% capacity loss per cycle (a total loss of capacitỹ 246 mAh·g −1 ) at the end of 500 cycles.

“…[14,[18][19][20] The pulse electrodeposition is a simple, economical, and an attractive method for the Sn-based electrodeposited coatings. [21][22][23][24][25] The co-deposition of nano-sized ceramic particles into metal matrix from an aqueous electrolytic bath is attracting a lot of interest due to its ability to produce films with enhanced mechanical properties. [7,8,10,11] The wear behavior of nano-crystalline materials has already received much attention in the past decade, and many experimental studies have reported a significant increase in the wear resistance of nano-crystalline materials due to grain refinement.…”

The Sn-based ZrSiO 4 nanocomposite coatings have been synthesized by pulse co-electrodeposition technique from an aqueous electrolyte containing SnCl 2 AE2H 2 O, C 6 H 17 N 3 O 7 , Triton X, and varying amounts of nano-sized ZrSiO 4 particles (0,5,10,15,20,25,30, and 35 g/L). As-deposited films have been analyzed using X-ray diffraction, scanning electron microscope equipped with an energy dispersive X-ray spectrometer, and transmission electron microscope. The microhardness, wear as well as corrosion property of the coatings have been also evaluated. It is observed that the surface morphology of Sn-ZrSiO 4 nanocomposite coatings is strongly dependent on the reinforcement concentration in the electrolyte, and the Sn-ZrSiO 4 nanocomposite solder deposited from the electrolyte containing 25 g/L ZrSiO 4 yields the highest hardness and the best wear and corrosion property among all the synthesized samples. The whisker growth propensity of the developed Sn-ZrSiO 4 nanocomposites has also been examined after 90 days of aging at room temperature and reported here.

“…The variation of frequency may change the texture and grain size of deposited layers [28]. Increasing the frequency by enhancing the nucleation rate can reduce the grain size of deposits [29]. This can be attributed to the formation of increased number of new nuclei on the cathode surface due to high overpotential applied under high pulse frequency conditions [27].…”

Composition modulated nanocomposite of NiFe-Mn-Al 2 O 3 coatings were fabricated on mild steel using single bath technique through alternative variation of duty cycle at constant frequency (VD) and repeated alteration of frequency at constant duty cycle (VF). The number of layers was 32 and thickness of each layer was 2.5 lm. The results of microstructure examination by SEM and EDS for VD coatings exhibited that Fe/Al 2 O 3 -rich layers adjacent to Mn rich ones were deposited in a frequent manner. In the case of VF coatings, alternative variation of frequency did not affect the chemical composition of matrix and only changed the content of embedded nanoparticles. The microhardness of Ni-Fe-Mn-Al 2 O 3 multilayers compared to monolithic and multilayer Ni-Fe-Al 2 O 3 of the same thickness was significantly increased because of Mn incorporation into the matrix. The corrosion resistance was found to be better for VD coating in comparison to the VF ones.
