Impaction of Graphite Type on Performance of Polycrystalline Diamond Powder

Abstract:

Taking different types of graphite as raw materials ， polycrystalline diamond powder is prepared by shock wave synthesis through copper to absorb and transfer the heat in the article. Yield and abrasion resistance performance are tested, and impaction of graphite crystallite structure on the yield and abrasion resistance performance is researched. As the result, diamond yield and abrasion resistance synthesized from scale graphite is not as good as from earthy graphite. It is easy for polycrystalline diamond powder synthesized from artificial graphite which crystallite has parallel coke-base to graphitize and difficult to get diamond. Yield of artificial graphite which crystallite has disorderly carbon black base is higher than that of earthy graphite, there are more pores for the first baked artificial graphite of carbon black base, the abrasion resistance performance of synthesized diamond is worse than earthy graphite, and the abrasion resistance performance of the second baked polycrystalline diamond powder is better than earthy graphite.
