摘要
通过观察纯净钢中稀土夹杂物的形态,测试电化学腐蚀EIS谱和极化曲线,研究稀土元素镧对纯净钢耐腐蚀性能的影响。试验结果表明,镧加入纯净钢中,可变质夹杂物和改善夹杂物形态,从而提高了纯净钢耐腐蚀性能。
Study is made of the impact of La on the corrosion resistance of pure steel through the observation of the morphology of RE inclusion in the pure steel, testing of electro-chemic corrosion EIS and polarization curve. The test results showed that addition of La into the pure steel can modify the inclusion and improve the morphology of the inclusion thus to improve the corrosion resistance of the pure steel.
