The development of Nickel-Cobalt alloys has been gaining interest in recent years as they present
mechanical and magnetic properties suitable for applications in electronic and magnetic devices. One of
the most used methods for manufacturing these alloys is electrodeposition, as it is a cheap and easy-toexecute process, as well as the possibility of controlling operational parameters. Thus, aiming to deepen
knowledge about these alloys obtained by the electrodeposition process, this work was developed through
a systematic review of the literature that made it possible to evaluate the parameters applied in Ni-Co alloy
electrolytic baths and the influence of these parameters on the magnetic properties. The methodology
was carried out in different stages: the first, with the establishment of keywords and search strings; the
second, searches in the Scopus Preview and Science Direct databases, adopting primary research articles
published from 2010 to 2023. After the search, inclusion and exclusion criteria were applied, limiting
the study to 10 articles. From reading the selected articles, it was possible to identify that the magnetic
properties of the Ni-Co alloy depend entirely on the operational parameters, the bath’s composition,
and the cobalt content in the coating. Studies also indicate that the crystalline structure of the alloy, pH
variations, and heat treatment can influence these properties.
