对10年前经离子注入处理过的GCr15轴承钢进行了时间特性的研究，重复了10年前所有的试验，结果表明，改性的宏观效果随时间的推移不仅是稳定的，还在原改性的基础上更有所提高。从对样品的AES分析中可看出，这种改性的进一步提高是由于掺杂元素注入到材料表面的初期，在其表面形成的是一些亚稳态结构，而使材料表面的性能有一定的改善。但随着时间的推移，材料表面的结构发生多元迁移，这种多元迁移的趋势是最终形成了稳定的金属合金或一些硬质含金。这方面的研究还需进一步的深入，但对离子注入材料改性的时间特性的研究会给离子注入技术的实用性提供理论与试验的依据。
The GCr15 bearing steel treated by ion implantation 10 years ago was studied for time characteristics and all the experiments 10 years ago were repeated. The results show that the macroscopic effect of the modification is not only stable but also the original modification On the basis of more improved. As can be seen from the AES analysis of the sample, further improvement of this modification is due to the doping element is injected into the surface of the material in the early stage, the formation of some metastable structure on its surface, leaving the material surface properties have certain Improvement. However, with the passage of time, the surface structure of materials undergoes multiple migration. The trend of multiple migration will eventually form a stable metal alloy or some hard gold. However, the study on the time characteristics of the ion implantation material modification will provide theoretical and experimental basis for the practicality of the ion implantation technology.
