Abstract

Abstract

This paper discussed the mechanism of metro stray current corrosion of pipelines buried underground to design a test plant of simulating stray current corrosion.By the simulating test, a new method of resisting stray current corrosion was developed, which various elements were permeated into the surface of steel pipes in low temperature.The result of comparison tests in same corrosive environment shows that the corrosion resistance of the materials after the low temperature gas multicomponent thermochemical treatment is improved greatly, a compound layer is found on the surface of steel pipes, by micromechanism analysis of corrosion resistance.
