摘　　要：通过电化学试验装置,测试45~#钢在高分子凝胶体系与纯水中的电化学腐蚀性能。通过开路电位、tafel曲线、阳极极化曲线等测量数据,分析45~#钢在高分子凝胶体系中的腐蚀特性。研究表明,45~#钢在聚丙烯酰胺凝胶体系中的腐蚀较为严重,但是随着有机高分子质量分数的增加,其腐蚀速率的增加幅度趋缓。The aim of this research was to investigate the electrochemical corrosion behavior of carbon steel in a gel system. Polyacrylamide （PAM）, a common water treatment polymer additive, was used as a simplified sludge gel simulant in present work. The electrochemical corrosion property of 45^# steel in gel environment and water environment was investigated using electrochemical techniques. The results show that in the presence of gel, corrosion rate of 45^# steel increased. With the increase of PAM, the increase rate of corrosion rate slowed.
