“…44 A similar surface morphology was observed on the Sn-Mn layers deposited from gluconate baths. 8,45 coatings obtained at the same potential E = -2.1 V vs. SCE, but from the electrolytes containing various concentrations of tin ions. In this case, BSE SEM images are presented.…”

“…Because of significant differences in the standard potentials of Sn and Mn, the potential of the Sn-Mn alloy can be adjusted by the appropriate alloy composition, potentially allowing protective characteristics similar to those of cadmium to be obtained. Moreover, Chen and Wilcox 8 have already studied the corrosion performance of tin manganese coatings electrodeposited from gluconate baths. They stated that Sn-Mn alloys containing more than 20 wt% of manganese, were as good sacrificial coatings as chromate passivated zinc-nickel alloy coatings.…”

The conditions for manganese with tin electrodeposition from aqueous citrate electrolytes were studied. Partial polarization curves were determined. The influence of applied potential, electrolyte composition and pH level, hydrodynamic conditions and quantity of charge passed, on the electrodeposition of Sn-Mn layers were determined. The surface composition of deposits was ascertained by chemical analysis (WDXRF). The morphology of coatings was studied by SEM. The phase composition of Sn-Mn samples was determined by X-ray diffractometry and Raman spectroscopy. The electrolysis parameters allowing electrodeposition of Sn-Mn coatings containing various amounts of Mn (in the range from about 0.5 wt% to 42 wt%) were selected. The morphology of deposits depends significantly on the content of manganese and on the parameters of electrolysis. The surface morphology of samples with Mn content of about 27 wt% is not uniform, two types of areas with significant differences in chemical composition are observed. XRD studies indicate that four crystallographic phases are formed in the deposits (β-Sn), MnO, Mn(OH) 2 , and MnSn 2 , while Raman spectroscopy revealed also the presence of α-MnO 2 , MnOOH, and SnO 2 , which are the products of chemical processes taking place simultaneously with electrolysis. The mechanism of the co-deposition of manganese with tin has been proposed.

“…[23][24][25][26][27][28] Recently, more interests in the preparation of manganese were triggered because of their use in high manganese (10-30%) and high strength automotive steel, also named high-Mn TWIP steel, which can lead to a reduction of the weight and improvement of the safety of cars. [28][29][30][31] However, the manufacturing of this type of steel commercially was still obstructed because of the high cost of the production of manganese.…”

In this work, remelted high carbon ferromanganese was chosen as a consumable anode to produce porous carbon monolith and low carbon ferromanganese at the same time by molten salt electrolysis. During potentiostatic electrolysis, the anode fed manganese ions and iron ions into molten salts, with porous carbon left at the anode and ferromanganese deposited on the cathode. The anode residue was characterized by Xray diffraction, scanning electron microscopy, Raman spectrum and transmission electron microscopy.Results indicated that this type of porous carbon material with a high degree of graphitization has a multimodal pore system consisting of micropores, mesopores and macropores, which is hierarchical carbide derived carbon (CDC). The anode and cathode current efficiencies are estimated to be at least 92% and 80%, respectively. All results implied that it is feasible to prepare carbide derived carbon monoliths with a hierarchical pore structure and low carbon ferromanganese simultaneously by molten salt electrolysis.
