摘要: 通过国产六面顶设备高压高温腔体组装结构研究,提出了大腔体烧结PDC材料存在的问题及有关对策.不同腔体组装结构对比实验结果表明,改进后的Ⅲ号腔体组装结构烧结PDC材料的平均磨耗比 为 12.3×10,其中心点相对边缘点耐磨性降幅仅为 19.2%,可实现φ25mm PDC材料的均匀烧结。

Abstract: By the study of the assembly structure of HP/HT cell of the Cubic Press, some sintering technical problems and the solutions in the use of the enlarged HP/HT cell were proposed. The test results of the samples sintered at different HP/HT cells show that the 25mm-diameter PDC sintered with the improved large HP/HT cell No3 possesses wear-resistance Q 12.3×104 with only 19.2% decrease from the peripheral point to the central point, therefore the even sintering of 25mm-diameter PDC material can be realized.
