Abstract

Abstract

Three kinds of synthetic diamond with different particle sizes were treated by cryogenic treatment, and the diamond particles before and after treatment were analyzed by Raman spectrum, fluorescence spectrum and static press tester. The results showed that the average static pressure strength of diamond 30/35 was increased by about 23.2%, while the internal residual stress was reduced by 25.93%. In conclusion, cryogenic treatment could reduce the magnetic properties of synthetic diamond particles and repair their defects. It also helped to release the internal residual stress and increase the static pressure strength.
