【Abstract】 The Fe-Nd-P alloy deposits with different Nd content were obtained by electrodeposition from acidic solution containing NdCl₃ at constant current density, and their morphologies and components were studied by SM and EDS. SEM examination indicated that the Nd content can reach up to 71.51　wt% in the Fe-Nd-P alloy deposits obtained from the H₃PO₃ solutions. By measuring the deposition rate, we studied how the deposition rate was affected by the concentration of metallic salt, complexing agent,current density, pH value and bath temperature. The optimum formula for the bath compositions and plating conditions were determined.更多还原
