| 摘 要： | 研究了V C双重离子注入合成纳米结构、相变和抗磨损机制．研究表明，注入后可改变钢的成分，V与Fe原子比最高可达到28％；形成了纳米相弥散强化结构和无序相强化结构．从而提高了钢表面硬度，表面硬度可提高23％～146％；抗磨损也有着明显的提高，磨损阻抗为未注入钢的2．2～3．6倍．

| Abstract: | Tribological performance, nano structure and the formation of superior tribological surface of V+C dual implanted steel are studied. Structures for steel strengthens are observed in V+C dual implanted steel by TEM. The hardness increased 70% 146% for V+C dual implanted steel. The ion implantation is being successfully applied in the development of ion implantated drills. As a result, metal ion implantation as an engineering tool is a powerful and relatively important technique. The mechanism for improvement of tribological performance will be discussed. |
