ELECTROCHEMICAL CORROSION BEHAVIOR OF 27SiMn STEEL IN AN ENVIRONMENT OF A LIGNITE COALPIT
27SiMn在矿井褐煤环境中的电化学行为

The electrochemical corrosion behavior of 27SiMn low-alloy steel in an environment of a lignite coalpit was studied in this paper.The result indicates that a mixture composed of the lignite and mine water behaves acidic which accelerates the electrochemical corrosion of 27SiMn low-alloy steel,though the mine water formerly belongs to a neutral solution.
