| 目的 研究 N,Ti,Al 离子注入对 304 不锈钢耐磨性的影响规律,为 304 不锈钢材料的改良提供参考。 方法 采用等离子注入技术,在不同剂量下对 304 不锈钢分别进行 N,Ti,Al 离子注入,对离子注入后的试样进行表面微观形貌观测、表面硬度测试、摩擦磨损性能测试,并与 304 不锈钢基材进行对比。结果 304 不锈钢经 3 种离子注入后,均能获得平整、致密,没有裂纹,具有一定光洁度的表面组织,但是注入剂量增大会引起表面起泡现象,形成多孔形貌,光洁度降低。 此外,3 种离子注入均能提高 304 不锈钢的表面硬度,且高剂量注入试样的硬度比低剂量注入试样更高,相较而言,N 离子注入使表面硬度的提高更明显。 相比未注入基材,注 N 与注 Ti 表面层的摩擦系数均变小,注 Al 表面层的摩擦系数反而变大,但磨损量都明显降低。 高剂量注 N、注 Al 试样的耐磨性均高于低剂量注入试样,而高剂量注 Ti 试样的耐磨性低于低剂量注入试样,但仍好于注 N、注 Al 试样。 结论 在相同实验条件与注入工艺下,N 离子注入对表面硬度提高最显著(剂量为 5. 0×1017 ions/ cm2 ),约提高 41% ;Ti 离子注入对耐磨性提高最显著(剂量为 3. 0×1017 ions/ cm2),约提高 6 倍。 |

| Objective To study the influence law of wear resistance for 304 stainless steel implanted with N, Ti, Al ions, in order to provide a reference for the improvement of 304 stainless steel. Methods The plasma implantation technology was used to implant 304 stainless steel with N, Ti, and Al ions respectively at different doses, and surface microstructure, surface hardness test and friction wear test were performed on each sample after ion implantation, and the results were compared with those of the 304 stainless steel substrate. Results The results showed that the samples of 304 stainless steel implanted with all 3 kinds of ions had a flat and dense surface without cracks and with a certain smoothness, but with increased implantation dose, the smoothness decreased because the excessive ion implantation could cause blistering and lead to a porous morphology. In addition, all three kinds of ions implantation could improve the surface hardness of 304 stainless steel, and the sample hardness with high-dose implantation was higher than that with low-dose implantation, in comparison, the improvement in the surface hardness of samples implanted with N ions was more obvious. Compared to the non-implanted substrate, the friction coefficient decreased after implanted with N or Ti ions, while the friction coefficient of sample implanted with Al ions increased, but the amount of wears on all implanted samples reduced significantly. The wear resistance of all the samples implanted with N, Al ions at a high-dose was higher than that of the samples with low-dose implantation, while the wear resistance of the sample implanted with Ti ions at a high-dose was lower than that of the sample with the low-dose implantation, however, it was still higher than that of the samples implanted with N or Al ions. Conclusion Under the same experimental conditions and implantation process, the N ion implantation improved the surface hardness most significantly (at a dose of 5. 0×1017 ions / cm2 ), by about 41% , while the Ti ion implantation improved the wear resistance most significantly (at a dose of 3. 0×1017 ions / cm2 ), by about 6 times. |
