不同压力温度条件下聚合的Si-Ni-B中介聚晶金刚石(PCD)抗压强度及组织特征研究

Compressive Strength and Microstructure of Si-Ni-B Bond PCD Produced at Various Temperature and Pressure

在一系列高温超高压条件下,制备了Si-Ni-B中介结合的聚晶金刚石(PCD),用压缩试验、X射线衍射分析、SEM、金相分析研究了PCD聚合的温度、压力条件对其抗压强度及组织特征的影响。

A Series of PCD (Polycrystalline diamond)samples with Si-Ni-B bin der were produced at various high temperatures and ultra-high pressures. The effects of temperature and pressure on the compressive strength and microstructure of PCD were analysed by compressive experiment, X-ray diffraction analysis, SEM observation and metallographic examination.
