Wear Characteristics of Binder-Less Nano-Polycrystalline Diamond and Cubic Boron Nitride

Abstract:

Wear characteristics of binder-less (single-phase) nanopolycrystalline diamond (NPD) and cubic boron nitride (BL-PcBN) were investigated by rubbing them against various ceramics such as SiO₂, Si₃N₄, Al₂O₃ and SiC. The wear rates of NPD and BL-PcBN against SiO₂ and Si₃N₄ at high speed rubbing (280-360 m/min) at a loading pressure of 55 MPa (starting condition) were considerably high, indicating the main wear process is a chemical reaction. BL-PcBN specimens were found to be worn at much higher (more than ten times) rates than NPD, suggesting that cBN highly reacts with these ceramics in comparison with diamond under the experiment condition.
