| 摘 要： | 在碳锰钢中添加单一稀土元素镧和铈,通过测试其腐蚀速度和点蚀特征参数值,考察了材料耐蚀性能的变化。结果表明,稀土对碳锰钢耐蚀性能的提高有作用,添加稀土所引起的组织变化是导致耐蚀性变化的主要原因。

| Abstract: | In this paper, experiments were made on carbon-manganese steel with La and Ce respectively to observe corrosion parameters such as rate of corrosion, pitting and so on. The results obtained indicate that the existence of rare earths has a positive effect on carbon - manganese steel in terms of corrosion resisting property. Furthermore, the change of mi-crostructure due to existence of rare earth is responsible for the effect on corrosion resisting property of the steel. |
