利用建立的断电流暂态测量系统和提出的由-t·dV/dt～lg(t)图判断腐蚀体系时间常数个数和弛豫过程类型的判断方法,定性地确定了钝化膜随时间的变化情况。用这项技术连续监测了20~#碳钢和1Cr18Ni9Ti不锈钢的小孔腐蚀破坏过程。
By using the established transient current measurement system and the proposed method of determining the number of time constants and the type of relaxation process from the -t · dV / dt ~ lg (t) diagram, the passivation films were qualitatively determined over time Changes in the situation. This technique was used to continuously monitor the pinhole corrosion failure of 20 ~ # carbon steel and 1Cr18Ni9Ti stainless steel.
