摘要/Abstract

摘要： 　以工业废铁屑作原料制备高纯度电解铁,并优化了在氯化物溶液中的电解工艺条件,所得样品纯度最高可达到99.983%.通过SEM断面形貌观察,该电解铁样品非常致密.交流阻抗及腐蚀速率测定表明,电解铁的纯度越高,其耐腐蚀性能越好.

Abstract: The high purity electrolytic iron was made from scrap iron chips. Electrolytic conditions of pure iron were determined in chloride baths and the highest purity was 99.983% by chemical analysis. Pure iron had very compact texture and high mechanical strength by SEM figures of cross section. In deaerated 0.5 kmol·m-3H2SO4 and 0.5 kmol·m-3NaCl solutions, the corrosion rate of iron decreased with increasing purity.
