【Abstract】 For the resistance characteristic of high porosity metal foam and the conversion from the change of current density with time to that with position distribution in plating area, a theoretical model has been established for the parallel electrodeposition of metal foam and anode under a constant situation to show the apparent current density distribution. The metal foam electrodepostion equipment was also optimized to keep the current density in the optimum range and the quality of metal foam guarranteed.更多还原
