| 中文摘要: |
| 研究微合金化对Cu-10Ni合金耐3.5%NaCl溶液冲刷腐蚀的影响。使用中频真空熔炼炉熔炼Cu-10Ni-1Fe-1Mn-X（X=0.2Al或0.2Ti）合金，使用相同的热处理及冷变形工艺制备样品后与Cu-10Ni合金一起进行冲刷腐蚀实验。通过扫描电子显微镜（scanning electron microscope，SEM）、X射线衍射仪（X-ray diffractometer，XRD）、电化学腐蚀、电化学阻抗谱（electrochemical impedance spectroscopy，EIS）、X射线光电子能谱仪（X-ray photoelectron spectrometer，XPS）、质量损失测试等对样品进行分析表征。结果表明：加入0.2Al/0.2Ti后的Cu-10Ni合金的耐冲刷腐蚀能力得到提高。这是由于在Cu-10Ni-0.2Al合金及Cu-10Ni-0.2Ti合金表面耐腐蚀膜中分别含有Al2O3、TiO2，提高了样品的耐冲刷腐蚀能力；Cu-10Ni-0.2Ti合金耐冲刷腐蚀能力略强于Cu-10Ni-0.2Al合金的，这是因为Cu-10Ni-0.2Al合金在Cl?富集的环境中易吸收Cl?，从而导致膜层有一定的裂纹。 |

| The effect of microalloying on erosion-corrosion resistance of Cu-10Ni alloy in 3.5% NaCl solution was investigated. Cu-10Ni-1Fe-1Mn-X (X=0.2Al or 0.2Ti) was melted in a medium-frequency vacuum melting furnace. After the samples were prepared by the same heat treatment and cold deformation process, erosion-corrosion experiment was carried out together with Cu-10Ni alloy. The samples were analyzed and characterized by scanning electron microscope (SEM), X-ray diffractometer (XRD), electrochemical corrosion test, electrochemical impedance spectroscopy (EIS), X-ray photoelectron spectrometer (XPS), and mass loss test. The results show that the erosion-corrosion resistance of Cu-10Ni alloy was improved by adding 0.2Al/0.2Ti. This was because that the surfaces of Cu-10Ni-0.2Al and Cu-10Ni-0.2Ti alloys contained Al2O3 and TiO2 respectively, which could enhance the erosion-corrosion resistance of the samples. The erosion-corrosion resistance of Cu-10Ni-0.2Ti alloy was slightly better than that of Cu-10Ni-0.2Al alloy, because the Cu-10Ni-0.2Al alloy was easy to absorb Cl? in a Cl? enriched environment, resulting in certain cracks in the film. |
