Alloys of iron group metals and tungsten, obtained by electrolytic deposition, have particular physical and mechanical properties. Evaluation of the different functional properties of binary and ternary alloys formed by these metals allows expanding possibilities of their practical application.  The composition, structure and mechanical properties of coatings deposited from boron-gluconate electrolyte at current densities 1-5 A/dm2 and solution temperature 80 °C were investigated. The morphology and composition of the coating were studied using NETSCAN-VEGA scanning electron microscope and system of elemental analysis INGA Energy DX. X-ray diffraction measurements were carried out by means of X-ray diffractometer DRON-IM1 (Fe-Co radiation, Mn filter) Microhardness was measured using PMT-3 microhardnessmeter. Tribological tests were performed on the friction machine under lubrication with reciprocating motion according the cylinder-plane procedure at a frequency of 280 double strokes per minute. The roughness was estimated by profilometer Surtronic-25 (Taylor-Hobson UK)  The average W content in the Fe-W alloys deposited at ic = 2-5 A/dm2 was 20 at.%. W content in the Co-W alloy depends on the electrolyte pH with the maximum- 23 at% reached at pH 6-7.  Addition of iron sulfate in the gluconate electrolyte results in deposition of Co-Fe-W alloys with the 10-20 at% W content, depending upon the FeSO4 concentration. Increasing of FeSO4 concentration from 4 to 7 g/l results in increase of iron quantity in the coatings from 13 at% to 30 atomic%. Optimal W content - 20 at% in alloy was obtained at ic = 5 A/dm2 and FeSO4 concentration – 4 g/l. The electrolysis conditions, the method of the electrolyte preparation, which determine the nature of the complexes formation in the bulk electrolyte and composition of the deposited alloy, affect the current density efficiency (CDE). At current density 2 A/dm2 CDE for alloys Co-W, Fe-W and CoFe-W was, respectively -75%, 80% and 90%. Increase of current density in the range of 2-7 A/dm2 results in CDE decrease from 90% to 65% for the first two alloys. At the same time CDE remains unchanged for Co-Fe-W alloy  The hardness of the Fe-W and Co-W alloys with 20 at% W, approximately, is similar to the chromium coating hardness. The Fe-W alloys hardness was higher than this of Co-W alloy. At ic = 1 A/dm2 Co-W alloy microhardness - 870 kg/mm2. At ic = 3 A/dm2 microhardness of Fe-W was 950 kg/mm2.  Hardness of the Co-Fe-W alloy with 30 at% iron content increased up to 650 kg/mm2.  The coatings were tested for wear in conditions of friction with lubrication. With the hardness of the alloys close to the hardness of chromium their durability was lower. The friction coefficient for CoFe-W and Fe-W was higher as compared with the of the Co-W alloy in the same conditions. Friction coefficient of the Co-W, Fe-W and Co-Fe-W alloys were - 0,07, 0,09 and 0,11, respectively.  After the test, the value of microhardness of Co-W and Co-Fe-W alloys, deposited at ic = 1 A/dm2 was higher and less for Fe-W alloy, as compared with microhardness of these alloys before testing. The difference in the friction coefficients and microhardness after wear can be caused by varying the structure of the oxides formed on the alloy surface.  The current density did not influence surface roughness of Fe containing alloys. Co-W alloy roughness changed to two times with a pronounced minimum at 2 A/dm2.  This work was supported by the Academy of Sciences of Moldova (project 15.817.02.05.A)
