大气腐蚀监测传感器的研究与应用

Research and Application of Atmospheric Corrosion Monitoring Sensor

通过实验室盐雾试验和沈阳地区户外大气环境中的现场试验研究了电极间绝缘膜厚度对双电极原电池传感器可靠性及测量敏感性的影响,及其在户外大气环境中的实用性。结果表明:适用于长期户外现场监测的传感器的最佳绝缘膜厚度为0.3~0.5mm;传感器监测结果与腐蚀挂片测试结果具有很好的线性相关性;传感器可以很好地应用于户外大气环境的腐蚀监测和研究。

The influence of the thickness of the insulating film between electrodes on the reliability and measurement sensitivity of dual-electrode galvanic cell sensor and its practicability in outdoor atmospheric environment were studied through laboratory salt spray tests and field tests in outdoor atmospheric environments in Shenyang. The results show that the optimal insulating film thickness for sensors suitable for long-term outdoor field monitoring was 0.3-0.5 mm, the sensor monitoring results had a good linear correlation with the corrosion coupon test results. The sensor could be well applied to corrosion monitoring and research in outdoor atmospheric environment.
