连续式热压烧结金刚石制品的研究

Study on diamond product sintered by continuous hot pressing

烧结是决定金刚石制品性能的关键环节。通过对比分析普通电阻式热压烧结工艺和连续式热压烧结工艺所获得的锯片试样,阐述了连续式热压烧结工艺制备金刚石制品的优越性。结果表明:连续式热压烧结工艺能降低产品的气孔率,提高致密度和质量稳定性;改善金属胎体对金刚石的包镶状况;减少烧结过程中的能耗和烟尘,对金刚石制品行业节能减排具有积极推动作用。

Sintering is the key to the performance of diamond products. Two kinds of sintering processes, namely continuous-hot pressing and traditional hot pressing, are studied by preparing saw blade samples with each of them. Results show that continuous-hot pressing has the advantages on preparation of diamond products, which does better in terms of density, performance stability and diamond-wrapped inlay ability. In addition, it can also decrease the power consuming and reduce emissions during preparation, which to some extent has a good effect in increasing energy efficiency and reducing emissions in the diamond product manufacturing industry.
