| 目的 确定快速化学镀 Ni-Zn-P 合金的工艺。 方法 通过一系列实验,研究主盐含量、pH 值、温度、时间等对镀层沉积速度及镀层锌镍比的影响,确定最优工艺条件。 借助 SEM,EDS,XRD 及电化学方法分析镀层微观形貌、成分及耐蚀性。 结果 在 ZnSO4·7H2O 8 g/ L,NiSO4·6H2O 35 g/ L,NaH2PO2·H2O20 g/ L,NH4Cl 50 g/ L,C6H5Na3O7·2H2O 70 g/ L,稳定剂 1. 5 mg/ L,pH=9. 0,温度 90 ~ 95 ℃ 的条件下,化学镀 Ni-Zn-P 合金沉积速度为 5 ~6 μm/ h,镀层中 Zn 质量分数为 8% ~ 10% ,P 质量分数为 6% 左右,Ni 质量分数为 80% ~85% 。 Zn 的存在使 Ni 呈现出晶态结构,在 XRD 谱图上 2θ = 45°及 2θ = 52°位置分别出现了 Ni(111),Ni(200)衍射峰。 施镀时间不会影响镀层成分,但会影响镀层耐蚀性。 施镀1. 5 h 时,镀层厚度约为 9 ~10 μm,其耐蚀性略好于相同厚度的 Ni-P 镀层。 结论 Ni-Zn-P 化学镀沉积速度较快,8% ~10% 的 Zn 使镀层中 Ni 呈晶态结构,且改善了镀层耐蚀性。 |

| Objective To determine a rapid electroless technique for Ni-Zn-P alloy coating. Methods The effects of the concentration of main salts, pH, temperature and electroless time on the deposition rate and Zn ° Ni (wt. % ) of coating were studied by a series of experiments. An optimized electroless technique for Ni-Zn-P alloy was achieved. The morphology, composition, phase structure and corrosion resistance of the coating were analyzed by SEM, EDS, XRD and EIS, respectively. Results Ni-Zn-P alloy coating was prepared on carbon steel by the electroless technique when ZnSO4·7H2O, NiSO4·6H2O, NaH2PO2·H2O, NH4Cl, C6H5Na3O7·2H2O, stabilizing agent, pH and temperature were 8 g/ L, 35 g/ L, 20 g/ L, 50 g/ L, 70 g/ L, 1. 5 mg/ L, 9. 0 and 90 ~ 95 ℃ , respectively. The deposition rate of the coating was 5 ~ 6 μm/ h. The contents of Zn, Ni and P in the coating were 8wt. % ~ 10wt. % , 80wt. % ~ 85wt. % and about 6wt. % , respectively. Besides, the Ni in the coating showed crystalline structure in the presence of Zn. The diffraction peaks of Ni (111) and Ni (200) appeared at 2θ = 45 ° and 2θ = 52 °. In addition, electroless time had slight influence on the coating composition, but could affect the corrosion resistance of the coating. The thickness of Ni-Zn-P alloy coating was about 9 ~ 10 μm when the electroless time was 1. 5 h. The Ni-Zn-P coating with a thickness of 9 ~ 10 μm had better corrosion resistance than the Ni-P coating with the same thickness. Conclusion The electroless deposition rate for Ni-Zn-P coating was higher. The presence of 8wt. % ~ 10wt. % Zn led to the formation of crystalline Ni in the coating, and improved the corrosion resistance of the coating. |
