RE重軌鋼在模擬工業大氣環境下的腐蝕行為

Corrosion behaviors of RE heavy rail in simulated industrial atmosphere

  • 摘要: 采用周期浸潤腐蝕實驗結合電化學方法研究了模擬工業大氣環境下RE重軌鋼的腐蝕行為.結果表明,RE重軌鋼的耐腐蝕性能優于不含RE的重軌鋼.RE重軌鋼中,RE合金元素在基體的局部富集促進了銹層中保護性好的α-FeOOH相的快速生成和含量的增加,提高了銹層阻止侵蝕性介質穿透的能力,改善了重軌鋼在工業大氣環境下的耐腐蝕性能.

     

    Abstract: The corrosion behavior of rare earth(RE) heavy rail steel was studied by a cycle infiltration corrosion test and an electrochemical technique under simulated industrial atmosphere. The results show that RE heavy rail steel has more excellent anticorrosive property than the other none-RE heavy rail steel. In RE heavy rail steel,α-FeOOH phase quickly forms and content increase in rust layer due to the enrichment of RE alloy elements in the matrix,RE alloy elements improve the ability of rust layer to prevent erosion of corrosive agent penetration,which improves the corrosion resistance of the heavy rail steel in industrial atmosphere.
