“…In fact, there have been some reports on magnetic films such as Ni, Co, Ni-Co, Ni-Co-Sn, Sm-Co, and Co-Pt prepared from DESbased baths, [3][4][5][6][7][8][9][10] and we have also reported Fe and Fe-Ni films prepared in DES-based plating baths. 11,12 In our previous studies, we confirmed that the plating processes from the DES-based baths for the Fe and the Fe-Ni films have high current efficiency (>90%).…”

We fabricated Fe-Co films from a deep eutectic solvent (DES)-based plating bath and investigated magnetic properties of the plated films. The plating baths were obtained by stirring the mixture of choline chloride, ethylene glycol, FeCl 2 Á4H 2 O, and CoCl 2 Á6H 2 O. The composition of the plated films depended on the amount of FeCl 2 Á4H 2 O in the plating bath, and Fe content of the films was varied from 0 to 100 at. %. Depending on the Fe content, the saturation magnetization and the coercivity of the films varied. The Fe 76 Co 24 film shows high saturation magnetization and smooth surface, and the change in the saturation magnetization shows good agreement with the expected change by the Slater-Pauling curve. High current efficiency (>90%) could be obtained in the wide film composition. From these results, we concluded that the DES-based plating bath is one of effective baths for the Fe-Co films with high current efficiency. V C 2015 AIP Publishing LLC.

“…3 Table 14 shows the conductivities observed in DESs which are comparable to ionic liquids; 44,45 DESs are therefore a highly investigated medium for electrochemical applications.

“…Hence, preliminary testing was carried out to assess the alloy corrosion behavior. This is primarily motivated by the potentially harmful effects associated with the high cytotoxicity of the byproducts generated during the corrosion process [17]. From the corrosion results (see Figure 11 and Table 3) it was found that the corrosion properties of the Co-20 wt.…”

Binary Co-Cr alloys containing various Cr contents were vacuum induction melted and cast into wedge-shaped copper molds. It was intended to develop a microstructure (1) free from interdendritic segregation and porosity; (2) having minimal intermetallic precipitates; and (3) suitable for biomedical applications. The resultant microstructures were evaluated from sections obtained longitudinally and centrally in the plane normal to the diverging wedge faces. All ingots showed a dendritic microstructure with some characteristic features. For instance, in Co-20-30 wt. % Cr alloys, the chilled cast microstructures consisted of columnar dendrites without interdendritic segregation, a minimum of intermetallic precipitates, and the presence of a predominantly athermal HCP ε-martensite (>80 vol. %). In addition, the metastable FCC γ-Co phase was identified by X-ray diffraction and scanning electron microscopy. In the case of 35-44 wt. % Cr cobalt alloys, a eutectic constituent including the σ-phase were found to develop in the interdendritic regions. From this work, a Co-20 wt. % Cr alloy was chosen for further investigation after heat treating below the γ/ε transition temperature. The resultant tensile strength and ductility were further improved after applying a heat treatment at 730 • C for 30 min, obtaining values of elongation of 26% as compared with 2.55 < 5 of elongation in the as cast condition. Also, the alloy corrosion resistance in artificial saliva was investigated. It was found that the exhibited corrosion rates for the as-cast and heat-treated conditions are between those reported for other similar systems.
