Study on the electrodepositing technology of Fe-Co alloy foil

In this paper,the technology of Fe-Co alloy foil electrodeposition from sulfate-chloride-tartaric acid electrolyte was investigated.The influences of current density,temperature,pH value and the constituents of the electrolyte on the compositions and the depositing rates of the alloy foil were discussed.The optimum technology of the electrodeposition was determined.The excellent Fe-Co alloy foils with thickness of 40-45μm and Fe content of 12.8%-33.5% were obtained.The morphology and the structure of Fe-Co alloy foil were measured and analyzed by means of SEM,EDS and XRD.The results show that the alloy foil surface is bright and smooth.The crystalline grains are fine,uniform and compact.The crystalline structure of the alloy foil is the Fe-Co solid solution faced center cubic(FCC),it shows(111),(200),(311) and(222) crystal texture with the(111) and(200) preferred orientation.
