Three types of cBN-based composites with TaN binder—without whiskers, with Al₂O₃ whiskers, and with SiC whiskers—have been produced by the high pressure-high temperature (HPHT) sintering. Density, hardness, Poisson ratio, and fracture toughness of the composites have been studied. The whisker-reinforced cBN-based composites exhibit a higher level of mechanical properties (hardness, fracture toughness) in comparison with the non-reinforced materials.

SiC和Al 2 O 3晶须对晶须增强的cBN基复合材料性能的影响

通过高压-高温（HPHT）烧结生产了三种类型的含TaN粘合剂的cBN基复合材料：无须，Al ₂ O ₃和SiC须。研究了复合材料的密度，硬度，泊松比和断裂韧性。与非增强材料相比，晶须增强的基于cBN的复合材料表现出更高的机械性能（硬度，断裂韧性）。
