| 摘 要： | 根据磨蚀理论,设计了一种含Ce耐磨耐蚀合金,用SEM、X-ray对磨损形貌进行了观察分析.结果表明,加入Ce可以获得致密化程度较高、分布均匀的组织,明显增加了合金碳化物中铬的含量,使碳化物的显微硬度提高,表面有CeFe7新相产生,并引起奥氏体、铁素体含量的增加,改变了试样表面的微观结构,从而提高了Fe-Ni-Cr合金的耐磨耐蚀性能. |

Effect of Ce on Corrosion and Wear Resistant Characteristics of Fe-Ni-Cr Alloy |
|
| Abstract: | Based on the corrosion and wear theory, a new corrosion and wear resistant alloy has been designed. The morphologies and microstructures of the wear surface were analyzed with SEM and X-ray. The results show that the addition of Ce can result in the relatively dense and homogeneous microstructure, increase the chromium amount in carbide and the micro hardness of carbide, some new phases were formed, and austenite contents increased and ferrite contents decreased on the surface of Fe-Ni-Cr alloy, which can improve the corrosion and wear resistance of Fe-Ni-Cr alloy. |
| Keywords: | cerium Fe-Ni-Cr alloy corrosion and wear resistance materials |
