【Abstract】 In order to prepare the continuous porous metal by electrodeposition, a mathematical model of continuous electrodeposition of strip porous metal under steady state was deduced,based on the transition from time variable to location variable.Furthermore the expression of apparent distribution for current density was derived. This relationship was verified experimentally from the preparation of porous nickel. When the angle between porous metal strip and anode configuration conformed to the same angle the apparent current density could be kept constant, and nickel crystal was compact.This work provided the theoretical foundation of on-line control in preparing porous metal by electrodeposition.更多还原
