研究了27SiMn在煤矿井下褐煤环境中的电化学腐蚀行为，结果表明，矿井水为中性溶液，与褐煤混合后混合物呈酸性，这一酸性介质加速了27SiMn的腐蚀． 27SiMn 褐煤 电化学腐蚀 液压支架
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 thich accelerates the electrochemical corrosion of 27SiMn low-alloy steel, though the mine water formerly belongs to a neutral solution.
