“…The EIS data is fitted by calculated by electrical equivalent circuit (EEC). The corrosion process of Ni-SiC composite coating can be replaced by EEC of R(Q(R(QR))) when the oxide layer on the substrate surface is taken into account [31]. As observed in Figure 9e, The EEC is consisted of the Rs modeling the solution resistance, in sequence with a constant phase element CPE1 in parallel with another resistance Rc modeling the coating resistance, and then another constant phase element CPE2 and the third charge transfer resistance of Rct associating with the corrosion process.…”

Nanoparticles reinforced metal matrix composite coatings have great application potential in mechanical parts surface strengthening due to their excellent mechanical properties. This paper reports a phenomenon that the grain orientation gradually evolves to (220) with the deposition current density increasing when preparing nanoparticles reinforced nickel-based composite coatings by jet electrodeposition (JED). During the preparation of Ni-SiC composite coatings, the deposition current density increases from 180 A/dm2 to 220 A/dm2, and TC(220) gradually increases from 41.4% to 97.7% correspondingly. With the increase of TC(220), the self-corrosion potential increases from -0.575 V to -0.477 V, the corrosion current density decreases from 9.52 μA·cm2 to 2.76 μA·cm2, the diameter of corrosion pits that after 10 days of immersion in 3.5 wt% NaCl solution decreases from 278~944 nm to 153~260 nm, and the adhesion of the coating is increased from 24.9 N to 61.6 N. Compared with conventional electrodeposition (CED), the Ni-SiC composite coating prepared by JED has the advantages of smooth surface morphology, corrosion resistance and strong adhesion, which is more obvious with the increase of TC (220).

Nanoparticle-reinforced metal matrix composite coatings have significant potential in mechanical part surface strengthening owing their excellent mechanical properties. This paper reports a phenomenon in which the grain orientation gradually evolves to (220) as the deposition current density increases when preparing nanoparticle-reinforced nickel-based composite coatings through jet electrodeposition (JED). During the preparation of the Ni-SiC composite coatings, the deposition current density increased from 180 A/dm2 to 220 A/dm2, and TC(220) gradually increase from 41.4% to 97.7%. With an increase of TC(220), the self-corrosion potential increases from −0.575 to −0.477 V, the corrosion current density decreases from 9.52 μA/cm2 to 2.76 μA/cm2, the diameter of the corrosion pits that after 10 days of immersion in a 3.5 wt% NaCl solution decreases from 278–944 nm to 153–260 nm, and the adhesion of the coating increases from 24.9 N to 61.6 N. Compared a conventional electrodeposition (CED), the Ni-SiC composite coating using JED has the advantages of a smooth surface morphology, high corrosion resistance, and strong adhesion, which are more obvious with an increase in TC(220).

“…Fe-P alloys have attracted the interest of researchers because of their magnetic and protective properties which highly depend on the amount of P. The electrodeposition of Fe-P alloy coatings suitable for various purposes like corrosion protection [12], electrical power equipment (transformers, rotating machines, etc.) [13] or electrocatalysis [14] has been explored by several researchers.…”

Pseudo-ordered macroporous iron-phosphorous (Fe-P) films have been electrodeposited potentiostatically from a citrate-sulfate bath onto Au surfaces pre-patterned with a colloidal crystal mask of polystyrene spheres of 350 nm in diameter. The electrolyte contained sodium hypophosphite as the P source, enabling the incorporation of 6-14 at.% P. For comparative purposes, continuous films have been obtained galvanostatically on unpatterned Au surfaces. In both cases, the P content could be varied to a certain extent by adjusting the deposition potential or current density. Tunable microstructure and magnetic response was observed due to the dissimilar chemical composition, with coercivity values being larger in the macroporous films. Additionally, wettability analyses showed that these were more hydrophobic, reaching contact angle values of about 130 ∘ . In spite of their hydrophobic character, the samples were catalytic toward oxygen evolution reaction (OER) in alkaline media. The macroporous Fe-P films showed faster kinetics for OER than their nonporous counterparts. Our results show that electrodeposited porous Fe-P based materials show an interesting combination of properties which make them appealing for applications including water cleaning, softmagnetic components, or electrocatalytic production of oxygen, to name a few.
