摘要
以人工合成金刚石及其相关材料与工具的制备研究为主线,基于其应用领域的不断拓展,将超硬材料的发展大致分为六个阶段或以产品种类划分为五大类产品(探索阶段、高温高压合成金刚石和c BN、单晶超硬刀具、PCD和Pc BN复合片、CVD合成金刚石技术、新型超硬材料),并对各发展阶段及相应产品进行了详细的概述。基于对超硬材料自身的性能、高性能被加工材料的发展、及提高切削加工效率和降低成本等3个方面的分析,详细讨论了超硬材料作为下一代切削刀具材料的优点和潜能。同时对超硬切削刀具的制造和应用过程中存在的一些潜在不足进行了探讨,并针对这些不足提出了可能的解决方案。
Development of superhard materials is divided into six stages or classified into five kinds of products （exploring stage ; synthetic diamond and cBN by high-pressure and high temper- ature （HPHT） technology; single crystal cutting tools; synthetic diamond by Chemical Vapor Deposition （CVD） technology; new superhard materials） according to the extending of application fields, and detailedly overviewed along to the main line of synthetic diamond and related materials and tools. The advantages and potential capacity of superhard materials seen as next generation materials for cutting tools are discussed from three aspects of their own performances, development of high performance machined materials, and improving machining efficiency and saving cost. Some potential limitations and possible solutions for superhard cutting tools in preparations and applications are also proposed.
