Abstract

Our research group has become specialized in the development and characterization of new baths for electrodeposition of pure metals and alloys since usual baths exhibit high toxicity and many additives in their composition. Among our desired systems lays the deposition of Fe-P alloys. The intention in investigating the baths for deposition of these alloys is the fact that they can be industrially applied because of their magnetic and corrosion resistance properties. Therefore, this project intends to optimize a lightly alkaline bath for the deposition of the Fe-P alloy on copper substrate, using NTA (nitrilotriacetate acid) as complexing agent, as an alternative to the conventional acid baths. The characterization of the Fe-P films obtained from this bath will be performed by SEM, EDX and XRD techniques. Furthermore, this project will contribute to the technological development of iron alloys. It is also worth to emphasize that the complexing agent NTA to be utilized in the composition of the electrodeposition bath of Fe-P alloys has a biodegradable aspect, so the environmental impact of its use is minor than that of conventional and alternative additives that have been employed.
