Effect of cobalt particle morphology on the properties of polycrystalline diamond composite

摘要: 选用类球形和晶须状的团聚钴粉（团聚粒度相近），外掺到金刚石微粉中，经过超高压高温（HPHT）合成聚晶金刚石复合片（PDC），研究钴粉形貌特征对PDC性能的影响。研究发现：2种形貌的钴粉在微观形状、孔隙度、磁性能、结晶性等物理特征方面具有显著差异；用其合成的PDC样品，在界面结合形态、界面WC异常长大情况、抗冲击强度、耐磨性等方面，差异明显，类球形钴粉合成的PDC明显比晶须状钴粉合成的PDC具有更好的综合性能。Abstract: Spherical and whisker-like cobalt particles were doped into the diamond powders to synthesize the PDC compacts under the HPHT conditions, to investigate the effect of their morphology on the properties of PDC. It was found that the two morphologies of cobalt powder have significant differences in physical characteristics, such as microstructure, porosity, magnetic properties, and crystallinity. When they were used to synthesize PDC samples, it was found that there were noticeable differences in interface bonding morphology, abnormal growth of interface WC, impact strength, and wear resistance. PDC synthesized with spherical cobalt powder had better comprehensive performance than PDC synthesized with whisker-like cobalt powder.
