摘要: |
冷喷涂过程的低温特性决定了其适合制备氧化敏感性的 Ti 及 Ti 合金涂层,由于 Ti 金属的难变形性,使得很难得到高质量的冷喷涂涂层。 国内外学者对冷喷涂制备 Ti 及 Ti 合金涂层开展了初步研究工作。 文中在大量文献分析的基础上对冷喷涂制备 Ti 及 Ti 合金涂层组织调控手段进行了分类总结。 目前,对冷喷钛及钛合金涂层的调控手段主要集中在喷涂参数、粉末状态、基体状态和喷嘴等 4 个方面。 除此之外,一些新兴的技术如原位喷丸辅助技术、温喷涂技术也被证明是一种有效的增强难变形粒子变形的技术。 未来对冷喷涂 Ti 及 Ti 合金涂层的研究既要注重冷喷涂工艺本身,又要加强与其他加工技术的融合。 |

Abstract: |
The low temperature characteristic of the cold spray process determines its suitability for the preparation of oxidation- sensitive Ti and Ti alloy coatings. Due to the poor deformability of Ti metal, it is difficult to obtain high quality cold spray coat- ings. At present, domestic and foreign scholars have carried out lots of research work on cold-sprayed Ti and Ti alloy coatings. Based on a large number of literatures, this paper classified and summarized the microstructure control methods of cold spray Ti- based coatings. The control methods of cold spray titanium coatings mainly focus on four aspects of spraying parameters: Powder state, substrate state, powder condition and nozzle. Some emerging techniques such as in-situ shot peening and warm spraying have also proved to be an effective auxiliary for enhancing particle deformation. In the future, the research on cold-sprayed Ti and Ti alloy coatings should focus on the cold-spraying process itself and integration with other processing technologies. |
