摘　　要：在700℃下对65Mn钢进行稀土硼共渗处理,利用金相显微镜以及能量散射光谱(EDS)研究其表面渗层的微观结构特征,分析其对耐蚀性和耐磨性的影响,并与常规850℃下渗硼处理进行对比。采用腐蚀实验和磨损实验,评估了CeO_(2)增强的65Mn钢渗硼层在含肥土壤环境中的耐蚀性和抗磨性能。实验结果表明,引入CeO_(2)纳米颗粒后渗层的结构更加均匀致密,这对提升渗硼层的耐蚀性和抗磨性能具有显著的改善效果。腐蚀测试结果表明,稀土硼共渗渗层表面没有出现裂纹,保持完整且致密,界面未见腐蚀迹象。磨损测试结果表明,稀土硼共渗渗层体积磨损量为常规渗硼处理的18.09%。At 700℃,rare earth boron co-permeation treatment was applied to 65Mn steel.The microstructure and characteristics of the surface coating were researched using metallographic microscope and energy dispersive spectroscopy(EDS).The effects on corrosion resistance and wear resistance were analyzed and compared with conventional boron treatment at 850°C.Corrosion and wear experiments were conducted to evaluate the corrosion resistance and wear resistance of CeO_(2)-reinforced 65Mn steel boronized layer in soil environment.The results showed that the structure of the coating became more uniform and dense after introducing CeO_(2) nanoparticles,which achieved a significant improvement in the corrosion resistance and wear resistance of the boronized layer.The corrosion test results showed that no cracks were found on the surface of the rare earth boron co-permeation coating,and it remained intact and dense with no signs of corrosion at the interface.The wear test results showed that the volume wear of the rare earth boron co-permeation coating was 18.09%of that of the conventional boron treatment.
