摘　　要：以普通硬质合金YT5的混合粉末为参照,研究了PEG喷雾制粒的YF06纳米WC-Co硬质合金粉末的压制压力、压坯密度和弹性后效关系。试验证明,其压制压力和弹性后效较YT5粉末都有显著的提高。Referencing the YT5 blending powder of the common cemented carbide,studied the relation of the pressing-pressure、presswork density and elastic after-effect of the PEG-added and sprayed WC-Co cemented carbide nanometer powder of .The test show that the pressing-pressure and elastic after-effect of the YF06 are remarkably higher than the YT5.
