伸線ダイス
Document Type and Number:
Japanese Patent JP6800160
Kind Code:
B2
Abstract:
A wear-resistant tool includes composite polycrystalline diamond as a core, the composite polycrystalline diamond being composed of polycrystalline diamond in which particulate diamond is directly bonded and non diamond carbon. The polycrystalline diamond in the composite polycrystalline diamond is three-dimensionally continuous in composite polycrystal and primary particles have an average particle size from 10 to 500 nm.
