化学镀镍磷合金工艺研究

化学镀镍磷合金由于其优良的性能在工业上得到了广泛应用。为改进传统工艺所存在的不足，采用乳酸－柠檬酸混合络合剂体系研究了络合剂、温度、ＰＨ值及稳定剂地沉积速度的影响。优选了一种最佳工艺。该工艺稳定、沉积速度高、成本低，所得镀层平整、光亮、孔隙率低、硬度高，具有很好的应用价值。

Study of Electroless Nickel-Phosphorus Plating Process

Electroless nickel-phosphorus alloy deposits have been widely adopted in industries for their excellent properties. In view of the weaknesses of traditional techniques, acidic system with mixed complexant of latic acid and sodium citrate was adopted. The effect of complexant, temperature, pH value and stabilizer on deposition rate was studied. A process has been optimized with strengths such as high stability, fast plating rate, low cost, smooth and bright deposits, low porosity and high hardness.
