摘要
采用动电位极化曲线、循环极化曲线研究了固溶温度对904L不锈钢在浓硫酸溶液中电化学性能的影响。结果表明,固溶温度对阴极的电化学行为影响不大,对阳极极化曲线则有较大的差异。固溶温度为1120℃,保温时间为0.5 h时,904L不锈钢的耐蚀性最好。
Electrochemical performance was studied for 904L stainless steel after solution treat- ment at different temperatures in concentrated sulfuric acid by means of measurements potentiody- namic polarization curve and cycle polarization curve. The results show that the solution tempera- ture has little effect on cathodic process, but varies the anodic polarization curve greatly. Whilst 904L stainless steel shows the best corrosion resistance after solution treatment at 1120℃ for 0.5 h.
