    摘要:

    本研究采用放電等離子燒結(jié)方法首次制備了超細(xì)氮化硼多孔纖維改善的WC-ZrO2復(fù)合材料。在添加了超細(xì)氮化硼多孔纖維之后，樣品的硬度和斷裂韌性同時獲得了提升。而個別成分樣品的楊氏模量則突破了復(fù)合材料混合法則的局限，高達(dá)692GPa，接近純WC的楊氏模量 700GPa。

    Abstract:

    In this study, using spark plasma sintering, an ultrafine porous boron nitride nanofiber-improved WC-ZrO2 composite was prepared. The obtained composites displayed superior properties in terms of hardness and fracture toughness. In particular, the Young’s modulus value increased but did not follow the rule of mixtures for most of ceramics-based composites (up to 692 GPa, close to 700 GPa of pure WC).
