摘要
研究含Ce的化学镀Co Fe B合金工艺。用恒电位法测定镀液的阴极极化曲线 ,用称重法分析镀液组成对沉积速度的影响 ,综合考察镀层表面质量及镀层与基体的结合力。结果表明 ,Ce加入后 ,化学镀Co Fe B合金镀液的稳定电位、阴极过电位、沉积速度、稳定性和镀层质量都得到了明显的提高。含Ce的化学镀Co Fe B镀液的最佳组成和操作条件为 :NFe∶NCo=1∶40 ;NaHB4 1 0 g/L ;Na2 B4 O4 ·10H2 O 4g/L ;Na2 C4 H4 O6 ·2H2 O 5 0 g/L ;Ce 1 0g/L ;温度 3 5℃ ;pH =13 ;装载量 1 0dm2 /L。
The plating process of electroless Co Fe B alloy with rare earth element cerium is researched The cathode polarization curves of the plating bath are measured by potentiostat method, the effect of the plating bath composition on the speed of plating is analyzed by weighing method, and the surface quality of the alloy coating and adhesion between the coating and matrix are synthetically investigated on the base of experiments The results showed that the addition of cerium in plating bath could remarkably improve the static potential, the cathodal overpotential, the depositing speed and the stability of plating bath, and the coating surface quality The optimum plating bath composition and operating conditions are N Fe ∶N Co =1∶40,NaHB 4 1 0 g/L,Na 2B 4O 4·10H 2O 4g/L,Na 2C 4H 4O 6·2H 2O 50g/L,Ce 1 0 g/L,temperature 35℃,pH=13,load 1 0 dm 2/L
