双向脉冲电源在黄金电铸工艺中应用的可行性研究

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。

Feasibility study of the application of bidirectional pulse power in gold electroforming process

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 e!ectroforming layer, get more fine grain, and higher hardness. A preliminary verification ex- periment about bidirectional pulse power was made,and it obtained from bidirectional pulse power is better than that was found that for gold electroforming, electroforming layer from unidirectional ones.
