“…7 On the contrary, a simple bath without strong complexing agent shows several benefits, such as high current efficiency and good bath stability. 5 A simple electrolyte consisting of boric acid, potassium, and zinc and manganese chlorides was proposed for Zn-Mn electrodeposition in the past decade, 8 and this electrolyte was chosen for examination in the present study. However, in order to obtain a Mn-rich deposit from a simple chloride bath, significant cathodic polarization or high deposition current density (c.d.)…”

Additives are necessary in the electrodeposition of Zn-Mn alloys at high current densities, in order to reduce the hydrogen evolution reaction and prevent dendrite formation. The influences of two aromatic aldehydes, 4-hydroxy-benzaldehyde and 3,4-dimethoxy-benzaldehyde, as additives in the Zn-Mn plating electrolyte, were examined in this study. The characterization of the coatings by scanning electron microscopy and X-ray energy dispersive spectroscopy, as well as an examination of the effect of the additives by electrochemical methods, indicated a complex involvement of additive molecules in hydrogen evolution, as well as in Zn 2+ and Mn 2+ reduction. Consequently, a levelling action could be achieved and the chemical composition of the Zn-Mn alloy tailored by the addition of the proper type and concentration of additive in the plating electrolyte.

“…Moreover, other peaks corresponding to (101) and (004) directions of Zn (JCPD Card: 04-0841) appear for the sample annealed at 350°C in an oven. The crystallite thickness, D, has been deduced from the full width at half maximum (FWHM) using the Scherrer equations [4]. The average grain size of the crystallites from the Zn-Co deposit after thermal treatment was 12 nm for zinc and 22 nm for zinc oxide.…”

“…Electrodeposited Zn alloys with Fe group metals have been shown to significantly extend the corrosion protection of steel with respect to conventional Zn coatings. Alloys with Zn confer sufficient corrosion resistance to steel that nowadays it is a common procedure for most industries, particularly the automotive industry [4].…”

In this study, the samples were electrolytic grown under identical conditions, using potentiostatic control. We have studied the structural and magnetic properties of the Zn-Co samples. The alloy composition, structure and morphology, the effects of the thermal treatment temperature and the magnetic properties were strongly dependent on the cathode potential during the electrodeposition process. Detailed XPS analysis indicates the presence of zinc oxide (ZnO) in the samples as-prepared and after thermal treatment. We have also obtained information about the evolution of the magnetic susceptibility and the curves of magnetic hysteresis subsequent during thermal treatment. The coercivities of the Zn-Co samples as-deposited and annealed at 350°C temperature increase after annealing.

“…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].…”
