摘要:

以人工合成金剛石及其相關(guān)材料與工具的制備研究為主線，基于其應(yīng)用領(lǐng)域的不斷拓展，將超硬材料的發(fā)展大致分為六個(gè)階段或以產(chǎn)品種類劃分為五大類產(chǎn)品(探索階段、高溫高壓合成金剛石和cBN、單晶超硬刀具、PCD和PcBN復(fù)合片、CVD合成金剛石技術(shù)、新型超硬材料)，并對各發(fā)展階段及相應(yīng)產(chǎn)品進(jìn)行了詳細(xì)的概述。基于對超硬材料自身的性能、高性能被加工材料的發(fā)展、及提高切削加工效率和降低成本等3個(gè)方面的分析，詳細(xì)討論了超硬材料作為下一代切削刀具材料的優(yōu)點(diǎn)和潛能。同時(shí)對超硬切削刀具的制造和應(yīng)用過程中存在的一些潛在不足進(jìn)行了探討，并針對這些不足提出了可能的解決方案。

Abstract:

Development of superhard materials is divided into six stages or classified into five kinds of products (exploring stage; synthetic diamond and cBN by high�瞤ressure and high temperature (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.
