Properties of electrodeposited Co–Mn films: Influence of deposition parameters

Obtaining Mn-Co Alloys in AISI 430 Steel from Lithium-Ion Battery Recycling: Application in SOFC Interconnectors

“…The solution was kept under stirring and heating at 80 • C for 2 h [41,[45][46][47][48][49]. After cooling to room temperature, the solutions were filtered and the pH adjusted to 3.0 [27,29,[50][51][52] with the addition of sodium acetate. 49].…”

“…49]. After cooling to room temperature, the solutions were filtered and the pH adjusted to 3.0 [27,29,[50][51][52] with the addition of sodium acetate. The concentrations of the electrolyte solutions from the recycling process were analyzed by Atomic Absorption Spectrometry (Intralab model AA-1275ª) and the results, S1 and S2, are showed at Table 3.…”

“…For "A" solutions, the cyclic voltammetry graphs are shown in Figure 1. It can be seen that for all solutions, the cathodic reduction current starts at around −0.8 V and grows as the potential becomes more negative, indicating the reduction of metal ions present in the solution [28,29,41,52]. According to Karpuz et al 2015 [29], the electrodeposition potential of Co-Mn alloy can be chosen based on values that produce reduction currents for both metals separately.…”

“…Application of protective coatings is a simple, efficient and cheaper method that inhibits the phenomenon of chromium poisoning and maintains a good specific electrical resistance. Co-Mn based spinels have been developed as a protective layer that improves the performance of ferritic steels and can be obtained by different methods [22] such as slurry coating [23], plasma spray [24], electrodeposition [25][26][27][28][29], and others techniques [30,31].…”

“…Electrodeposition technique involves the deposition of a metal or alloy film over a conducting surface by electrolysis from a well-formulated electrolyte known as a bath, which can be an aqueous simple salt solution or a complex salt type [32]. Karpuz, Kockar and Alper (2015) [28] investigated the effect of deposition parameters, such as electrolyte concentration and pH, deposition potential and film thickness. They demonstrated that microstructure and grain size are very dependent on these parameters, especially pH.…”
