| 中文摘要: |
| 阐述了电火花微纳米涂层的形成机理及其表面性能研究,分析了熔覆层硬度、耐磨性得到改善的主要原因即纳米晶硬质相的加入,并重点论述了微纳米涂层中纳米晶组织的形成原因,即骤冷骤热的熔覆过程对金属表面层进行了超高速淬火。 此外,还指出了电火花微纳米技术存在的问题以及未来的主要研究方向。 |
| 英文摘要: |
| Forming mechanism and the surface properties of the micro nanostructured coating are introduced briefly in the article, and the main factors leading to the improvement of hardness and wear resistance of the cladding coating are analyzed , namely the join of nanometer crystal hard phase. It focuses on the causation of nanocrystalline organization existed in the micro nanostructured coating, that is the surface layer of the metal are ultra high speed quenched because of the shock chilling and shock heating in the cladding process. At the same time, the problem currently existed in electro-spark micro nano technology is discussed and future research interests are correspondingly proposed. |
