Recently, tungsten alloys with iron group metals have emerged as an alternative to replace electrolytic chromium, which involves environmentally hazardous synthetic procedures. Research on Fe-W alloys is very appealing, since such coatings have a unique combination of mechanical, corrosion and magnetic properties, even at elevated temperatures [1]. From this point of view, Fe-W alloys could be considered as suitable materials for certain micro-/nano-electromechanical systems (MEMS/NEMS). A series of Fe-W coatings have been electrodeposited from ammonia free glycolic-citrate bath. By changing the electrodeposition condition (i.e., pH, temperature and current density) the W content can be varied from 6 to 25 at% in a controlled way. Variations in W content as well as in current efficiency are discussed based on complexes distribution in electrolyte.  Mechanical properties of electrodeposited alloys have been determined using nanoindentation techniques on the cross-section of the specimens, and the magnetic properties of Fe-W alloys have been studied using Vibrating Sample Magnetometer (VSM).  XRD analysis showed that the grain size of Fe-W alloys decreases with the increase in W content in the alloys. Actually, structure of the films transforms from nanocrystalline to amorphous-like. This leads to an increase of hardness, which is as high as ~10 GPa for the alloy with the highest W content. Remarkably, hardness is lower than for Co-W [2], but higher than in Ni-W when the tungsten content is the same as in Fe-W [3]. The saturation magnetization Ms, coercivity Hc, and squareness ratio (i.e., Mr/MS, where Mr is the remanent magnetization) also vary with the W content: increasing of W content leads to the reduction in saturation magnetization and the coatings become magnetically softer.   Acknowledgments: Authors acknowledge funding from H2020 (project SELECTA 642642), the Research Council of Lithuania (MIP-031/2014), the Generalitat de Catalunya (2014-SGR-1015), the Spanish Ministry of Science and Competitiveness (MAT2014-57960-C3-1-R, co-financed by the Fondo Europeo de Desarrollo Regional), and the Moldavian national project (15.817.02.05A).
