目的研究由乙二胺四乙酸二钠(EDTA-2Na)、乙二胺四亚甲基膦钠(EDTMPS)和柠檬酸三铵(C_6H_5O_7(NH_4)_3)组成的复合配位剂,在不同浓度及pH下,对金沉积速率、镀金液稳定性、金镀层结构及性能的影响。方法用化学镀的方法在树脂基体上先预镀覆Cu-Ni-Pd金属层,然后制备金镀层。采用正交实验法,研究复合配位剂浓度及pH对金层沉积速率、镀金液稳定性、结合力、光亮度的影响。借助扫描电镜及能谱,分析不同优化组合镀液配方制备的镀层形貌及成分。结果以镀金沉积速率为评价指标时的最优组合为A_2C_3D_3B_2,以镀液稳定性为评价指标时的最优组合为A_2C_2B_3D_2,以镀层结合力为评价指标时的最优组合为A_2D_2...

The work aims to study effects of the compound coordination agent consisting of Disodium Ethylenediamine Tetraacetate (EDTA-2Na), Sodium Ethylenediamine Tetramethylene Phosphonic (EDTMPS) and Ammonium Citrate (C_6H_5O_7(NH_4)_3) on deposition rate, stability of plating solution as well as structure and properties of gold plating provided with different concentration and pH. The Cu-Ni-Pd metal layer was pre-plated on resin substrate by electroless plating, and then the gold plating was prepared. The effects of concentration and pH of compound coordination agent on deposition rate of gold platin...
