| Abstract: | With the increasing use of various electric equipment, the rate of corrosion leakage is going up yearly. The phenomenon leads to the heavy economic loss, and contaminates environment. The paper deals the corrosion mechanism of the stray current and finds the way of discharge, and provides references for the prevention of stray current for the engineering application. |
