Composition Structure and Properties of 25mm-Diameter Polycrystalline Diamond Composite
Source abstract
Abstract
The composition and structure of the polished cross section of 25mm-diameter PDC were investigated by SEM, Raman spectrum and XRD. The interface structure and the distri- bution of bonding phases of the polished vertical section of the PDC were analyzed by EDW, EDX, and the properties of the combined-interface of the PDC were measured by shear, quenching and compression test. The test results show that the 25mm-diameter PDC possesses properties as follows: transverse rapture strength σb 1160MPa; heat-resistance temperature 742℃; bond- ing strength τ2.67GPa; average wear-resistance Q 12.3×104 with only 19.2% decrease from the peripheral point to the central point.
