Magnetization behaviour of electrodeposited Zn-Mn alloys

Review—Zn–Mn Electrodeposition: A Literature Review

“…10,52 Magnetic properties.-Despite the interesting magnetism character of Zn-Mn system, there are scarce reports dealing with the characterization of magnetic properties of Zn-Mn alloys. The single attempt to investigate this field has been made only by Ananth et al 84 Taking into account that Mn is paramagnetic and Zn is diamagnetic, these authors 84 investigated the magnetic properties of Zn-Mn alloys. When measuring the magnetization M, it has been demonstrated that Zn-Mn system is highly sensitive to variations of plating parameters.…”

“…When measuring the magnetization M, it has been demonstrated that Zn-Mn system is highly sensitive to variations of plating parameters. 84 In this study, the effects of the deposition parameters, namely the current density, Zn 2+ /Mn 2+ ratio and additives on the magnetic properties coatings were deeply discussed. It has been documented that an increase in Zn 2+ ions in the bath lowers the magnetism of Zn-Mn alloys.…”

“…It has been documented that an increase in Zn 2+ ions in the bath lowers the magnetism of Zn-Mn alloys. For instance, Ananth et al 84 stated that, with very low Zn 2+ concentration of 10 g l −1 in the bath, Zn-Mn deposits assume a strong magnetic character. It has been stated that the contribution from the diamagnetic Zn atoms appears to be quenched by the adjacent manganese spins.…”

“…These Zn-Mn alloys have been extensively studied (Bozzini et al, 2011;Bucko, Mišković-Stanković, Rogan, & Bajat, 2015;Bucko, Rogan, Stevanovic, Stankovic, & Bajat, 2013a;Close et al, 2016;Ganesan, Prabhu, & Popov, 2014;Griskonis, Fanigliulo, & Sulcius, 2002;Fashu et al, 2015;Marin-Sanchez, Ocon, Conde, & Garcia, 2014;Wykpis, Bierska-Piech, & Kubisztal, 2014) because they offer good corrosion resistance (Bozzini et al 1999;Claudel et al, 2019;Ganesan et al, 2014;Louki & Feki, 2017a, 2017b, weldability, paintability (Fashu et al, 2015), appearance (Silva, Schmitz, Spinelli, & Garcia, 2012), mechanical properties, particularly plasticity (Bozzini et al, 1999) as well as hardness, tensile and compressive strength and improved passivation behavior in chloride medium (Bozzini et al, 1999;Díaz-Arista et al, 2009;Bucko, Lacnjevac, & Bajat, 2013b). Furthermore, there is a particular interest in these Zn-Mn alloys in the automotive industry (Ananth & Parthasaradhy, 1996;Muller, Sarret, & Andreu, 2003a;2003b;Silva et al, 2012) and for steel cable and plate coatings because they offer better adhesion between steel and polymer blends and easy adhesion of paint-even when the Mn content is low (Bozzini et al, 1999).…”

“…Moreover, this Mn electronegativity leads to significant but low efficiency hydrogen evolution reaction (HER) (Bozzini et al, 1999;Díaz-Arista et al, 2009). According to Ananth and Parthasaradhy (1996), the Zn-Mn system is so complex that the Mn content in the alloy can range from 0 to 100%.…”
