- 摘要:
- 采用电沉积法制备了不同锡含量的Ni-Sn合金。通过扫描电镜、X-射线衍射分析了镀层的形貌和结构。采用阳极极化曲线、交流阻抗测试、浸泡实验研究了Ni-Sn合金在人工海水中的腐蚀行为。结果表明：所制得的Ni-Sn合金镀层为Ni相晶态结构，Ni-7.72wt %Sn合金镀层在人工海水中的腐蚀电位最正，电化学反应电阻最大，耐蚀性最佳。浸泡实验结果表明，Ni-7.72wt % Sn合金在人工海水中耐蚀性与SUS304相近，优于Ni-P合金。
- Abstract:
- Ni-Sn alloys with different tin contents were prepared by the electrodeposition method. SEM and XRD were used to characterize the surface morphology and structure of the alloys. The corrosion behavior of the Ni-Sn alloys in artificial seawater were studied with anodic polarization, electrochemical impedance spectroscopy （EIS） and immersion test. The results indicated that the prepared coating was Ni of the crystal structure, and the Ni-7.72 wt% Sn alloy coating had the most positive corrosion potential, the highest electrochemical reaction resistance and the best corrosion resistance in artificial seawater. The results of immersion experiments showed that the corrosion resistance of Ni-7.72 wt%Sn alloy in artificial seawater was close to SUS304 and superior to Ni-P alloy.
