ABSTRACT
The hereby work presents the tribological properties of the iron-nickel alloys and their
dependence on the microstructure and thickness of the probes as well as the presence of an
external magnetic field during the synthesis. Coatings were electroplated on the brass and
copper metallic substrates using galvanostatic deposition in the same electrochemical bath
condition (Fe and Ni sulfates) and the electric current density. The surface morphology of the
films was observed by Scanning Electron Microscopy. The average composition of all FeNi
coatings was measured using Energy Dispersive X-ray Spectroscopy. Tribo-mechanical
properties such as microhardness, roughness, and friction coefficient were determined in the
obtained structures. The morphology and tribologial properties of the FeNi coatings clearly
depend on both the substrate (Cu, CuZn) itself and the presence of an external magnetic field
(EMF) applied during the deposition process.
