摘要
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 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.
