利用自制的实验室降雨模拟装置,研究了雨水pH值和降雨强度对A3钢的腐蚀和冲刷行为影响,同时用ACM(atmospheric corrosion monitor)监测了降雨期间的腐蚀速率变化.结果表明,A3钢的腐蚀速率随着模拟雨水pH值的升高而降低,其变化规律与失重结果一致,表明用ACM监测A3钢在降雨条件下的腐蚀速率在一定程度上是可行的.A3钢的冲刷量随着模拟雨水pH值的升高表现为先降后升的规律,从腐蚀产物的变化分析了其产生的原因.随着模拟降雨强度的增大,A3钢的腐蚀速率和冲刷量增大.等量模拟降雨条件下,冲刷量也随降雨强度的增大而增大,这表明降雨的冲击作用对A3钢的腐蚀和冲刷行为有显著影响.
