| 随着科技的迭代升级，对高性能光学窗口的需求日益凸显，金刚石光学窗口在电子、信息、航天等领域具有巨大的应用前景。目前金刚石窗口面临着性能要求高、连接难度大、传统钎焊材料难以满足需求的难题。本文对CVD金刚石光学窗口钎焊研究现状和发展趋势进行了论述，从金刚石使用的钎焊材料着手，分别介绍了Ni基、Cu基、Ag基3种不同类型的钎焊材料在金刚石钎焊中的应用现状。对Ag基钎料钎焊金刚石光学窗口过程进行了重点阐释，概述了添加不同种类合金成分的Ag基钎料对钎焊过程中组织形成及焊缝性能的影响，并探讨了单步及多步降熔法对减轻银铜基钎焊接头应力集中的作用机制。分析了Ni基与Cu基钎料因钎焊温度较高而容易产生严重的石墨化问题以及因存在较大的残余应力而不适用于窗口钎焊的原因，总结了不同钎料及钎焊工艺在窗口钎焊过程中存在的问题。最后探讨了目前Ag基钎料在钎焊金刚石窗口过程中仍存在的问题并提出了解决方案，并对金刚石窗口钎焊连接的未来发展进行了展望。 |

| With the iterative upgrading of science and technology, the demand for high performance optical windows is becoming more and more outstanding. Diamond optical windows contain great application prospects in electronics, information, national defense, aerospace and other aspects. At present, diamond windows are facing the status of high performance requirements, difficult connection, and difficult to fulfill the demand of traditional brazing materials. This paper addresses the current status and development trend of research on CVD diamond optical window brazing. Three types of brazing materials, Ni-based, Cu-based and Ag-based, are introduced in the application of diamond brazing. The process of brazing diamond optical windows with Ag-based brazing materials is mainly emphasized. The effects of adding different kinds of alloying components to Ag-based brazing materials on the organization formation and weld properties during the brazing process are outlined. The use of silver-copper based brazing materials to alleviate the problem of high stress and concentration in the joint by single-step and multi-step melting down methods is introduced. The reasons why Ni-based and Cu-based brazing materials are not suitable for window brazing due to the serious graphitization problems and the existence of large residual stresses at high brazing temperature are analyzed, and the problems of different brazing materials and brazing processes in the window brazing process are summarized. Finally, the problems that still exist in the brazing of diamond windows with Ag-based brazing materials are discussed and solutions are proposed, and the future development of diamond window brazing connection is also prospected. |
