“…7, line b, could be attributed to the shift of the peak of plane (100), and related to the distortion of the crystal lattice. On the other hand, peaks seen in pure Zn deposits remain but with lower intensity, indicating the presence of a zinc-rich (g-phase) ZnCo alloy [65] since the diffraction pattern of the ZnCo solid solution g-phase is very similar to the pure-Zn diffraction pattern [66]. These results are confirmed by the composition analysis presented in Fig.…”

Effect of aromatic aldehydes on the electrodeposition of ZnCo alloy from cyanide-free alkaline-gluconate electrolytes

The effects of vanillin and anisaldehyde on electrodeposition of zinc-cobalt alloys onto AISI 1018 carbon steel were studied in an alkaline gluconate zincate electrolyte. The influence of an additive on the metal discharge depends on the structure of the added molecule and on the nature of the substrate. The composition of the deposit varies during the electrodeposition process. Maximum cobalt content is observed close to the steel-ZnCo interface for ZnCo formed with or without vanillin, but the composition profile becomes more uniform when anisaldehyde is added to the bath. The morphology of Zn-rich Co-alloy coatings was evaluated: Cobalt ions produce porous ZnCo alloys; vanillin induces slightly porous deposits, whereas uniform and more compact deposits were observed with anisaldehyde. Furthermore, a crystallographic study showed that the orientation of the lattice planes changes, with highly oriented deposits produced in the presence of anisaldehyde.

“…A large number of authors have observed -phase coexisting with either or -phase when the zinc content of the alloy exceeds the solubility limit of zinc in the -phase. 30,31) However, the baths used by them contained either sulfates, or chlorides with NH 4 Cl causing higher pH as compared to our chloride baths. Therefore, lower pH of chloride baths containing boric acid without NH 4 Cl seems useful for preparing single-phase alloys comprising -phase.…”

Deposition of Nanocrystalline Zinc-Nickel Alloys by D.C. Plating in Additive Free Chloride Bath

et al. 2007

Nanocrystalline zinc-nickel alloy coatings were electro-deposited in chloride bath containing ZnCl 2 (50-200 gL À1 ), NiCl 2 .6H 2 O (50-200 gL À1 ) and H 3 BO 3 (40 gL À1 ) at 45 C. The initial alloy composition, as investigated by voltammetry, chronopotentiometry or EDX analysis, exhibited a pronounced dependence on the composition of plating bath. However, the alloy composition tended to approach an upper limit of 18 atomic percent when deposits grew thicker, for most of the plating bath compositions. The process was clearly the anomalous codeposition, which was considered to be due to the formation of an adsorbed layer of Zn(OH) 2 containing nickel cations, as an intermediate product, whose composition determines the composition of the electro-deposited alloy. The electro-deposited coatings comprised of single-phase structure of -phase (Ni 5 Zn 21 ) for about 12-18 atomic percent nickel and a mixture of -and -phases (hcp) for nickel atom percent below 8. The grain size decreased from about 50 nm to 20 nm with decrease in nickel content away from the stoichiometric composition of Ni 5 Zn 21 along with a decrease in hardness from about 450KHN to 150KHN. The decrease in hardness with a decrease in grain size seems attributable to the grain boundary sliding as predominant deformation mechanism. Anodic dissolution of the alloys involved pronounced dezincification, forming -phase (fcc) that dissolved at the end.

“…It was reported that hydrogen evolves from an epoxy polymer solution on steel and Zn-coated steel at almost the same rate, but the wettability of Zn-alloy surface by polymer solution is smaller as compared to steel surface. As a consequence of the greater contact angle, hydrogen accumulates on the Zn-alloy cathode during electrodeposition of epoxy film, and a more porous epoxy structure is formed on this substrate [6].…”
