摘要
采用PGSTHT30型电化学工作站,对不同种类的ODS钢在1mol/L的硫酸溶液中的电化学腐蚀特性进行了研究,测量了极化曲线和自腐蚀电位,对腐蚀形貌进行了分析。研究表明:弥散强化合金随着Cr含量的增加,能够有效提高耐蚀性。
The electrochemical corrosion properties of different oxide dispersion strengthening（ODS） steels were investigated in 1mol/L H2SO4 solution by means of electrochemical workstation（PGSTHT30）.The polarization curve and free-corrosion potential of candidate materials were measured.The microstructure of the corroded materials was analysed.The results indicated that the ODS steel with high chromium content has the superior corrosion resistant.
