【摘要】：复合超硬材料作为一种性能优异的结构材料,被越来越广泛地应用于切削加工、油气钻探等领域.目前大部分复合超硬材料是通过高温高压方法制备.本文主要介绍了近年来复合超硬材料的高压合成与研究取得的成果和进展,重点包括纳米、亚微米、微米聚晶金刚石与立方氮化硼、立方相氮化硅-金刚石超硬复合材料以及金刚石-立方氮化硼超硬合金(复合)材料等,这些新型的复合超硬材料已经被成功合成,各种性能检测表明这些复合超硬材料的硬度、热稳定性等主要性能已明显超越传统超硬材料,可成为有广阔应用前景的新一代复合超硬材料.文中还介绍了近些年研究复合超硬材料出现的一些新的思路、方法与途径,并对复合超硬材料的进一步研究做出了展望.
[Abstract]:As a structural material with excellent properties, composite superhard materials are more and more widely used in machining. At present, most of the composite superhard materials are prepared by high-temperature and high-pressure methods. This paper mainly introduces the achievements and progress in the synthesis and research of composite superhard materials at high pressure in recent years, with emphasis on nanometers, submicron, etc. Micron polycrystalline diamond and cubic boron nitride, cubic silicon nitride diamond superhard composites and diamond cubic boron nitride superhard alloy (composite) materials have been successfully synthesized. All kinds of performance tests show that the hardness, thermal stability and other main properties of these composite superhard materials are obviously superior to those of traditional superhard materials. This paper also introduces some new ideas, methods and approaches to study the appearance of composite superhard materials in recent years, and makes a prospect for further research on composite superhard materials.
