The results show, when pitting corrosion occurred on the brass surface, the polarization resistance of electrode was obviously decreased, and the corrosion potential being also obviously lowered.
结果表明，黄铜表面出现点蚀时，电极的极化电阻明显下降，腐蚀电位也明显降低。

A electrode system for detecting the corrosion of brass tubes in service is made. Brass tubes in simulated circle cooling system are studied with the electrode system.
