Analysis on Research of the Surface Nanocrystallization of Metallic Materials

金属材料的表面纳米化处理是近几年表面强化方法研究的热点之一。这种技术将纳米晶体材料的优异性能与传统工程金属材料相结合,在工业应用上具有广阔的应用前景。通过对表面纳米化的基本原理、制备方法、结构特征和功能特性的综述,提出要实现这种新技术的工业应用需要解决的问题,如影响因素,表面纳米化形成动力学等。

The surface nanocrystallization of metalmaterials is one of popular research method about surface strengthing in recent years. This kind of technique combine together the excellent function＂ of nanocrystal materials with the traditional engineering metal materials, and have very widely applied foreground in the industry. The present research condition of surface nanocrystallization is summarized, including the basic principle of surface nanocrystallization, preparation method, the structure characteristic and the function characteristics, and the way to bringing the technique about industrialization is putted foreword such as The factors affecting nanocrystallization and formation dynamics of nanocrystallization.
