| 中文摘要: |
| 目的 研究 N80 钢在含有石英砂的不同浓度 NaCl 溶液中的冲刷腐蚀行为。 方法 采用扫描电子显微镜( SEM) 、能谱分析( EDS) 等手段分析腐蚀产物的结构及相组成,通过失重法计算腐蚀速率。 结果 腐蚀产物主要为 FeO 及 Fe3O4。 结论 随 NaCl 浓度的增加,N80 钢的腐蚀速率加快,当 NaCl 质量分数超过 7% 时,出现明显的点蚀。 |

| Objective To study the erosion and corrosion resistance and behavior of the N80 steel in NaCl solutions of different concentrations with 10 wt% solid particles. Methods The erosion and corrosion products were analyzed by means of SEM and EDS, and the corrosion rate of the N80 steel was studied by the weight-loss method. Results The corrosion products of the steel were mainly composed of FeO and Fe3O4. Conclusion The corrosion rate of the N80 steel accelerated with the increasing NaCl concentration, and pitting was formed on the surface of the sample when the concentration of NaCl was over 7 % . |
