摘要
讨论了热压金刚石工具材料的包镶力和致密性。建立并运用热压金刚石工具材料热压烧结后期的密度及致密化方程 ,分析了热压烧结各主要工艺参量及物理参量。对Fe ,Ni,Co包镶金刚石 ,以及主要粘结相 6 6 3Cu ,Co,复合Fe粉 ,复合Co粉等胎体材料进行了差热分析实验 ,验证了该密度及致密化方程的正确性 ,并用于指导生产实际 ,使生产出的热压金刚石工具材料的实际使用性能及其稳定性得到了有效的提高。
The wrapped force and the densification of the hot pressed sintered matrix composites for the diamond tools (HPSMCDT) were discussed, the density and densification equation group for the hot pressed sintered later stage of HPSMCDT were established and applied, the various technological and physical parameters with the equation group were thoroughly analyzed. The test of the differential thermal analyses (DTA) with the composites of Fe, Ni, Co wrapped up the diamonds, the principle adhensive phase as 663Cu powder, composite as Fe composites and Co composites was carried out. The correctness of the density and densification equation group established was verified. These researches were used in the actual hot pressed sintered technology for the diamond tool composites, the actual performance index and the related stability of the HPSMCDT were radically improved.
