目前，黄金首饰的电铸工艺在不断地改进，而电铸所用的电源还是以单向脉冲电源为主，电铸工艺改进大都集中在电解液配方方面。双向脉冲电源可以通过电源参数的调节来改善电铸层的物理性能，相对于单向脉冲电源具有很大的优势，可以使电铸层的整平性进一步提高，会得到晶粒更加细小，硬度更高的电铸层。文中采用双向脉冲电源对黄金电铸进行了初步性实验研究，其结果表明，可以得到比较理想的电铸层。
Nowadays,the technique of electroforming of gold jewelry has been improving .However,unidirectional pulse power remains the main power used in electroforming industry and the improvement techniques are mostly con -fined to the formula of electrolyte .Bidirectional pulse power can be used to improve the physical properties of the elec-troforming layer by adjusting the parameters of the power ,showing great advantage over unidirectional power .It can im-prove the leveling of the electroforming layer ,get more fine grain,and higher hardness .A preliminary verification ex-periment about bidirectional pulse power was made ,and it was found that for gold electroforming ,electroforming layer obtained from bidirectional pulse power is better than that from unidirectional ones .
