摘要
随着《中国制造2025》战略的实施,制造领域对先进工具的加工精度与加工效率要求不断提升。钎焊金刚石工具因金刚石与钎料合金间具有良好的界面结合特性而备受学术与工业界的广泛关注。如何有效增强金刚石与基体间的界面结合强度并同时减少钎焊过程中金刚石的热损伤,是当前钎焊金刚石工具的研究焦点。本文详细阐述了钎焊金刚石的界面结合机理、金刚石热损伤机制以及钎焊金刚石工具失效抑制策略方面的国内外研究进展,并对未来钎焊金刚石工具的研究方向进行了展望,以期为高性能加工工具的设计开发提供参考。
With the implementation of‘Made in China 2025’strategy,the requirements for processing accuracy and efficiency of advanced tools in manufacturing field are continuously improved.Brazed diamond tools have attracted extensive attention from academia and industry because of the good interfacial bonding characteristics between diamond and filler alloys.How to effectively enhance the interfacial bonding strength between the diamond and the matrix and to reduce the thermal damage of the diamond during the brazing process is the current research focus of brazed diamond tools.In this paper,the research progress on the interfacial bonding mechanisms,thermal damage mechanisms of brazed diamond and failure inhibition strategies of brazed diamond tools are elaborated,and the future research direction of brazed diamond tools is suggested,which is expected to provide reference for the design and development of high-performance machining tools.
