Corrosion reasons of stray current during metal anode electrolyzers running;

Research on distribution rule of the stray current in the pits;

Design of reducing corrosion to electrolysis system by reduction in stray current;

Tows the power supply system in view of the URT transportation to use the rails backflow to have the stray currents question,unifies the DC 1500V power supply service pattern power supply to be away from long,the voltage drop small merit,proposed uses the DC 1500V fourth rail technologies to come the question which the thorough settlement stray currents produces.

This article analyzes the reasons why the stray currents occur and their harm to subway equipment and facilities and proposes preventing and controlling measures for the subway stray currents.

Lab experiments on alternate stray current corrosion;

Automatic monitoring system of stray current corrosion for urban express railway;

On the basis of chlorine ion concentration in the environment and the polarity voltage positive offset data of the buried metal structure influenced by stray current,by adopting artificial neural networks' method,a prediction model of dangerous degree of stray current corrosion for metro was proposed.

Compared with raw materials and zinc-plating samples, the corrosion resistance of material after multicomponent thermochemical treatment was analyzed by simulating test of stray current corrosion.
