摘要:: 研究了稀土对４５钢固体硼氮共渗工艺、渗层成分、组织、耐磨性及断口形貌的影响。试验结果表明，稀土的加入使渗速增大，渗层中Ｂ，Ｎ含量特别是Ｎ的含量增加，硼化物针齿变得细密、直长；且ＦｅＢ的相对含量减少，Ｆｅ２Ｂ相增加，渗层耐磨性提高，同时稀土增加了过渡区厚度，减少裂纹源。生产应用证明，稀土硼氮共渗可使烟机配件的使用寿命大幅提高。

Abstract:: The impact of rare earth on the co -seepage process of 45 steel solid boron nicotin, osmotic composition, tissue, abrasion resistance, and fracture shape. The test results show that the addition of rare earth increases the seepage speed, B, and the content of N content in the infiltration layer increases, especially the N content of N, and the boronic needle tooth becomes fine and straight; and the relative content of the FEB decreases, the FE2B phase increases, the penetration layer has increased abrasion resistance, and the thick soil increases the thickness of the transition area to reduce the crack source. Production applications have proved that rare earth boron -nicotin penetration can greatly improve the service life of hood machine accessories.
