| 摘 要： | 用正交试验法确定了加稀土硼氮共渗工艺参数及稀土加入量，用金相显微镜、X射线衍射仪及SAM观察和分析了渗层组织、相结构及微区成分；将加稀土硼氮共渗样与硼氮共渗样进行磨损试验，结果表明：加稀土后耐磨性能明显提高；渗层脆性及硼化物致密度得到改善；渗层中碳、氮含量提高，增强了硼化物与基体的结合强度。生产实践表明：加稀土硼氮共渗的使用寿命较普通硼氮共渗处理的提高20％。

| Abstract: | The optimum process parameters and quantity of RE were chosen by orthogonal tests method .The microstructure ,phase composition, micro-composition were observed and analysed by means of optical microscope ,X-ray and SAM .The test of wear resistance between boronitriding and boronitriding added RE sample was done .The results show that wear resistance of boronitriding added RE sample is better than that of boronitriding sample, brittleness and microstructure of boride layer is improved , concentration of the nitrogen and carbon in the layer is up so that it strengthen combining of matrix and boride .It is also showed by use that the serves life of cigarette machine fittings treated by RE-boronitriding is 20% more than that by boronitriding,and is three to five times greater than that of treated by nitriding . |
