“…Accordingly, potentials as negative as -1.6V vs. SCE could be used to obtain deposits of zinc alloys with metals such as Mn. Similar XRD results were observed by Sylla et al [32]. They reported a Mn content of 1% wt in a Zn-Mn alloy deposit obtained from a chloridebased acidic bath containing PEG as an additive.…”

“…Electrodeposited alloys of Zn, such as Zn-Ni, Zn-Co and Zn-Fe, present higher corrosion resistance than pure zinc coatings. Also, it has been reported in the literature that Zn-Mn alloys show even better corrosion resistance properties [31][32][33][34]. The high corrosion resistance of these alloys is likely due to the dual protective effect of manganese: on the one hand Mn dissolves first because it is thermodynamically less noble than Zn, thereby protecting Zn; and on the other hand Mn ensures the formation of compounds with a low solubility product over the galvanic coating.…”

“…Although it has been reported that among the Zn alloys those of Zn-Mn show the highest corrosion resistance, their deposition process presents some drawbacks related to the bath instability and current efficiency. Among the various electrolytic baths and additives proposed to obtain Zn-Mn alloys, the use of a chloride-based acid bath with polyethylene glycol (PEG) as the additive seems very promising [31][32][33].…”

Electrodeposition of Zn–Mn alloys in acidic and alkaline baths. Influence of additives on the morphological and structural properties

et al. 2005

Electrodeposition of Zn-Mn alloys on steel was achieved using alkaline pyrophosphate-based baths or acidic chloride-based baths. Cyclic voltammetry was used to determine the potential ranges where the various redox processes were taking place. It appeared that the reduction of Mn(II) was generally hidden by the other reduction reactions, especially by the hydrogen evolution reaction. Zn-Mn alloys containing up to 25 at.% Mn in the alkaline bath and 12 at.% in the acidic bath could be obtained at the cost of very low current efficiencies.The characterisation of the deposits obtained either by galvanostatic polarisation or potentiostatic polarisation was performed by Scanning Electron Microscopy and X-Ray Diffraction. Various Zn-Mn phases were obtained, depending on the current densities, the composition of the deposit and that of the electrolytic bath.Two commercial additives usually used for zinc electrodeposition, one in alkaline baths, the other in acidic baths, were tested. Their effects upon the composition, the morphology and the microstructure of the deposit were investigated.

In this study, the kinetics of Zn–Fe codeposition was investigated in chloride acidic solution using cyclic voltammetry. Anomalous codeposition is detected and this mechanism depends on the Zn(II)/Fe(II) concentration ratio in the electrolytic bath. Influence of deposition parameters on the morphology and structure of the coatings is discussed using characterization techniques and using the anodic linear sweep voltametry (ALSV). The ratio between Zn(II)/Fe(II) considerably influences the structure of the alloys. Dense, uniform, and single‐phased Zn–Fe coatings could be obtained.
