黄铜管腐蚀监测传感器的研制

设计制作了用于对电厂凝汽器H70/30黄铜管进行监测的传感器。采用电厂实际使用过和未经使用的黄铜管制作电解池，用制作的传感器测量了黄铜管的电化学阻抗谱和极化阻力。结果表明，该传感器可以用于对黄铜管的腐蚀进行监测。

STUDY ON THE SENSOR FOR MONITORING BRASS TUBE CORROSION

A sensor for monitoring corrosion of brass tube of power station is designed and made.The Ag/AgCl wire is used as reference electrode and the Pt-Ir alloy wire as assistant electrode.Insulatedly,the two electrodes are filled in a tailor-made EVA(polymer of ethylene and acetic acid ethylene)tube whose diameter is one millimeter.So the sensor can be put into long tube for monitoring.A simulation cell is made for simulating the condition of power station.The used and not used brass tubes are cut into same length for making cell.The inside of brass tube is used as work electrode,the tap water is used as electrolyte.The sensor is applied to measure polarization resistance( R p) of the two brass tubes of cell.The results show that the sensor can be used for monitoring the corrosion of brass tube.
