ESEM, polarization curve and EIS indicated that the corrosion rate of the substrate and the loading of the oxide coating (i.e. Ir content) increase with etching time at the initial stage and then decrease. The oxide coating on the substrate pretreated by suitable etching pretreatment is of a uniform and compact surface which has large electrochemical active surface area, fine electrocatalytic activity for oxygen evolution and high stability. Key words： oxide anode    etching    oxalic acid 收稿日期: 2004-11-04      ZTFLH:  TG172   服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 初立英 许立坤 吴连波 王廷勇 王均涛 陈光章 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y2005/V41/I7/763 [1] Trasatti S.
