Foam iron material has a low-cost , rich in raw materials , and environmental pollution . Have broad applications in composites , electromagnetic shielding devices , electrochemical collector materials , insulation materials, filtration and purification materials . The structure and function of the integration of new green multi-purpose material in this paper using electrodeposition prepared foam iron material . The selection and ratio of the various parameters of the material preparation process , including the electrolyte composition ( main salt and auxiliary salts , additives , etc.) , the process operating conditions (current density , electrolyte temperature, the power supply waveform) . Through the bath and the material properties (including the current efficiency and tensile strength, the electrodeposition uniformity, pliability ) to determine the best process scheme . Experiment by the single factor of the individual ingredients , finalized a new process of preparation of the foam iron , ferrous chloride ( FeCl 2 < / sub> ) 220 g / L ; ammonium chloride (NH 4 Cl) 200 g / L; manganese chloride ( MnCl 2 < / sub> ) 20 g / ; citrate ammonium of (C 6 H 17 < / sub > N 3 O 7 < / sub >) 40 g / L ; pH 4.0 5 .0 ; temperature 60 6 5 ℃; A/dm2 current density of 10 high-temperature reduction temperature range : 920 9 60 ° C . Paper electrodeposition common impurity ions such as calcium ion , magnesium ion , sulfate ion impact on the material properties of the corresponding research identified three common allowable concentration of impurity ion content , wherein , Mg 2 , SO 4 2 - of concentration a maximum of 50 mg / L , the of Ca 2 < / sup > calcium should not be higher than 250 mg / L. Under conditions of a DC current , through this process , the average the electrolyte cathode current efficiency more than 95% , significantly improved throwing power . Foam iron tensile strength to achieve an average 8 kg / cm 2 , flexibility can be achieved the winding diameter 18.5 mm no obvious crack . The prepared material with porous structure, and have relatively good mechanical properties .
