Abstract: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.
Key words: diamond tool composite; hot pressed sintered; wrapped force; densification
