Precipitation of abrasion resistrant Fe-Ni alloy coatings from sulfate electrolytes

The abrasion resistant Fe-Ni alloys were precipitated on the surface of the blades of woodworking tools by electroplating from sulfate electrolyte. The elemental composition and surface morphology of the coatings were studied by energy dispersion X-ray microanalysis and transmission electron microscopy. The microhardness of obtained coating of Fe-Ni alloy has reached 400 HV that is 2 times greater than the microhardness of the substrate. It had been found that coating of Fe-Ni alloy on knife-edge of woodworking tools reduces the wear by 50% ormore compared with the uncoated blades
