The erosion-corrosion behaviors of Z2CN19·10N austenitic stainless steel in a 3.5-wt% NaCl solution with various sediment contents (7 wt%, 10 wt%, 20 wt%) and flow rates (1 m/s, 3 m/s, 5 m/s) were studied using a rotary disk erosion-corrosion test device, scanning election microscopy (SEM), potentiodynamic polarization test and potentiostatic polarization test. The results showed that sediment concentration had a smaller influence on the electrochemical corrosion behavior of Z2CN19·10N stainless steel than the flow rate and that the flow rate mainly affected the pitting potential and passivation range, but it had little influence on the potential-constant polarization. When the erosion velocity was lower than 5 m/s, mechanical erosion was the main influencing factor, and no critical flow velocities appeared.

Z2CN19·10N奥氏体不锈钢在不同含沙量（7 wt%、10 wt%、20 wt%）和流速（1 m/s、3 m/s）3.5 wt% NaCl溶液中的冲蚀腐蚀行为, 5 m/s) 使用转盘侵蚀腐蚀试验装置、扫描电子显微镜 (SEM)、动电位极化试验和恒电位极化试验进行研究。结果表明，含沙量对Z2CN19·10N不锈钢电化学腐蚀行为的影响小于流速，流速主要影响点蚀电位和钝化范围，对电位恒定极化影响不大。 . 当冲刷速度低于5 m/s时，机械冲刷是主要影响因素，没有出现临界流速。
