- 本文采用旋转冲刷实验装置研究945钢在含泥沙海水中的冲刷腐蚀性能,测试介质为青岛附近海域天然海水并加入不同含量的石英砂模拟海水泥沙,分别采用电化学方法检测材料的抗冲刷腐蚀性能、失重法测量腐蚀速率、扫描电子显微镜(SEM)表征金属表面腐蚀产物形貌,并采用X射线衍射仪(XRD)、电子能谱仪(EDS)分析腐蚀产物成分。结果表明,含砂量0.3wt%条件下945钢的阻抗最大,冲刷腐蚀作用最低,随含砂量由0.15wt%增加到1.0wt%,腐蚀产物中的SiO2含量逐渐增加。当海水流速由1 m/s增大到5 m/s时,945钢的阻抗逐渐减小,腐蚀情况愈加严重,腐蚀产物成分主要为FeO(OH)。
- Abstract:
- In this paper, the erosion-corrosion properties of 945 steel in seawater with sediment content were analyzed with a rotary scouring test device. The test medium is natural seawater in the sea near Qingdao containing different content of quartz sand, which was used to simulate the sea sand. The erosion-corrosion performance of the steel was measured by electrochemical method, the corrosion rate was measured by weight loss method, the surface morphology was observed by SEM, and the corrosion product composition was analyzed by XRD and EDS, respectively. The results indicated that 945 steel showed the highest impedance and the lowest erosion when the sand content of 0.3wt%, and the SiO2 content in the corrosion product gradually increased with the sand content increased from 0.15wt% to 1.0wt%. When the flow rate increased from 1 m/s to 5 m/s, the impedance of 945 steel decreased gradually and the corrosion was more serious, the main components of the corrosion products were FeO(OH).
