| 中文摘要: |
| 目的 研究 Ni-Fe-P 化学镀层抗 CO2 腐蚀性机理。 方法 通过 SEM,EDS,XRD 以及 EIS 等技术对经化学镀 Ni-Fe-P 处理后的 35CrMo 钢表面进行表征,分析其抗 CO2 的腐蚀性能。 结果 处理后的35CrMo 钢表面为非晶态组织,硬度高达 570. 12HV。 Ni-Fe-P 镀层钢腐蚀倾向减小,极化电阻增大,镀层对基体形成了较好保护。 镀层的腐蚀过程受溶液双电层和钝化膜的影响。 结论 Ni-Fe-P 镀层在 CO2 水溶液中具有极强的钝化倾向,可显著提高材料的抗 CO2 腐蚀性能。 |

| Objective To investigate the mechanism of CO2 corrosion resistance of Ni-Fe-P coating. Methods By means of SEM,EDS,XRD and EIS, CO2 corrosion resistance behavior at the surface of 35CrMo with Ni-Fe-P coating was characterized and analyzed. Results The results showed that after Ni-Fe-P coating, the surface of 35CrMo was turned into amorphous microstructure and its hardness reached up to 570. 12HV. The polarization resistance increased and the corrosion tendency decreased, which provided good protection for the matrix. During the corrosion process, the corrosion behavior of the coating was affected by electric double layer capacitance and passivated film. Conclusion The Ni-Fe-P coating could significantly improve the resistance to CO2 due to its great passivation tendency in CO2 solution. |
