研究了镍的直流电铸和脉冲电铸的不同形式电流及其参数,同时,结合铸层表面形貌的影响分析,发现脉冲电铸在采取相对较大电流密度时,电铸质量和效率均优于直流电铸,实验优化后得到的占空比为10%,频率为1 000 Hz,平均电流密度为4 A/dm2.最后,利用优化的电流参数实现了不同微结构的电铸成型.

Through direct current electroforming and pulse current electroforming experimental research on nickel metal with different forms of current and different parameters,Meanwhile,considering the electroforming layer surface topography,pulse electroforming takes advantages over direct current on electroforming quality and efficiency when adopting big current density comparatively.Optimized pulse current parameters based on experiments as follows: dutyfactor 10%,frequency 1 000 Hz,average current density 4 A/dm2.Finally,we carried out the electroforming of different micro-structures with such parameters.
