| 钢轨的腐蚀关乎铁路运营效益和运输系统的安全等重大问题，重轨钢的耐腐蚀性同强度、硬度、耐磨性一样重要，应高度重视对重轨钢耐腐蚀性能的研究。介绍了国内外重轨钢的研究，主要概述在重轨钢加入Cr、Nb、Cu、Si、Mn、Ti、Al、Cr或Ni等不同合金元素，对重轨钢耐腐蚀性能的影响。介绍不同组织(珠光体、贝氏体、马氏体、奥氏体)的重轨钢，以及这些组织对重轨钢耐腐蚀性能的影响，并说明了不同的热处理或加工工艺对重轨钢耐腐蚀性能好坏的影响。最后结合重轨钢腐蚀机理、锈层形成机理和电化学过程以及影响金属大气环境腐蚀的主要因素，提出了几点提高重轨钢耐腐蚀性的研究方向。 |
| 英文摘要: |
| The corrosion of steel rails is related to many major problems such as railway operation efficiency and safety of transportation systems, so the corrosion resistance of heavy rail steel is as important as the strength, hardness and wear resistance. At present, there is little research on the corrosion of heavy rail steel, and the research on the corrosion resistance of heavy rail steel should be highly valued. The research on heavy rail steel at home and abroad was introduced and the effects of different alloying elements such as Cr, Nb, Cu, Si, Mn, Ti, Al, Cr or Ni on the corrosion resistance of heavy rail steel were summarized. The heavy rail steel with different microstructures (pearlite, Bayesian, martensite and austenite) was described and the influence of these microstructures on the corrosion resistance of the heavy rail steel was analyzed. Moreover, the influence of different heat treatment or processing technologies on the corrosion resistance of heavy rail steel was also clarified. Finally, combining the corrosion mechanism of heavy rail steel, the formation mechanism of rust layer and the electrochemical process, as well as the main factors affecting metal atmospheric corrosion, several research directions to improve the corrosion resistance of heavy rail steel were put forward. |
