This study deals with the electrodeposition of cadmium incorporated Cobalt–Nickel magnetic alloy as monolayer and multilayers. Magnetic alloys have been electrodeposited on commercial copper plates from chloride-based electrolyte under the controlled deposition condition. Co–Ni–Cd monolayer coatings were electrodeposited from two different cadmium concentrations (0.1 and 0.2 M) whereas multilayer coatings were electrodeposited with and without the addition of sodium hypophosphite in the electrolyte. Microstructural properties of the prepared alloy coatings were studied using X-ray diffractogram, and energy dispersive X-ray analysis (EDAX) spectrum, which reveals the development of nano deposits with appropriate elements. Field emission scanning electron microscopy (FE-SEM) micrographs of the alloys confirm nanostructure formation in both mono and multilayer coatings. Magnetic and corrosion properties of the coatings have been analyzed using the magnetic hysteresis loop (M–H plot) and immersion corrosion method. From this study, magnetic properties of cadmium incorporated coatings found to be closely related to magnetic elements, which leads to a significant change in the corrosion performance.

这项研究涉及作为单层和多层的镉结合钴钴镍磁性合金的电沉积。磁性合金已经在受控的沉积条件下从氯化物基电解质中电解沉积在商用铜板上。用两种不同的镉浓度（0.1和0.2 M）对Co-Ni-Cd单层涂层进行电沉积，而在电解质中添加或不添加次磷酸钠的情况下，对多层涂层进行电沉积。使用X射线衍射图和能量色散X射线分析（EDAX）光谱研究了制备的合金涂层的显微组织性能，揭示了具有适当元素的纳米沉积物的发展。合金的场发射扫描电子显微镜（FE-SEM）显微照片证实了在单层和多层涂层中均形成了纳米结构。已经使用磁滞回线（MH图）和浸入腐蚀法分析了涂层的磁性和腐蚀性能。通过这项研究，发现掺镉的涂层的磁性与磁性元素密切相关，这导致腐蚀性能发生了重大变化。
