摘要
应用烧结加热等静压和烧结-热等静压两种工艺制备了粗晶WC-15Co、WC-22Co和微晶WC-12Co-1Cr3C2、中等晶粒WC-12Co硬质合金,从原理、经济性论述了这两种工艺的差异及其对WC-Co硬质合金组织和性能的影响。结果表明,烧结-热等静压制作的硬质合金孔洞消除了,并且硬质合金的抗弯强度和弯曲疲劳寿命也大幅度提高。
Coarse-grain WC-15Co, WC-22Co and micro grin WC-12Co-1Cr3C2, mediumgrain WC-12Co cemented Carbide were made by sintering and HIP and sintering-HIP.The difference of two processes and the effect of process on structure and properties of WC-Co cemented Carbide were studied from technical and economical points of view. The results showed that cemented carbide manufactured by sinter-HIP is free of porosity and transverse-rupture strength, bending fatigue life are also greatly increased.
