Even Sintering of 25mm-Diameter Polycrystalline Diamond Composite

Abstract

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.

Key words: polycrystalline diamond composite, sintering, assembly
