| 摘 要： | 研究了火花等离子烧结工艺与YG10、YG12两种纳米硬质合金性能的关系.然后采用火花等离子烧结技术制备了硬质合金功能梯度材料,该材料由纳米WC/10%Co、纳米WC/12%Co、微米WC/15%Co混合粉以及不锈钢圆片烧结而成.显微硬度压痕显示该材料各层间的应力较小.

| Abstract: | The density, hardness and fracture toughness of YG10, YG12 nano hardmetals prepared by different spark plasma sintering processes were measured. A functionally graded material(FGM) was also produced by spark plasma sintering technology(SPS), and sintering powders of nano WC/10%Co, nano WC/12%Co, micro WC/15%Co and disk of stainless steel. The SPS processing led to FGM free of internal stress, which was measured using Vickers indentations. |
