中文摘要：

摘要在高温高压（5．0GPa、1500℃）的条件下，以Ni7。Mn25C05合金为烧结助剂，采用粉末混合法制备了金刚石复合片（PDC），并采用SEM及Micro-Ramanspectroscopy对金刚石烧结体进行了形貌及物相测试。结果表明，由于烧结腔体存在压力、温度梯度，金刚石在经历高温高压烧结后，具有多种烧结形态及物相结构，表现为晶形完整的金刚石微晶、纳米石墨相和无定形碳。

英文摘要：

Under the high temperature and high pressure （5.0 GPa, 1500 ~C） conditions, PDC was prepared by mix-powder method using Ni70 Mn25 Co5 alloy as sintering aids. SEM and Micro-Raman spectroscopy were used to investigate the morphology and structure of diamonds sintered body, and the results show that the diamonds, after sintering at high pressure and high temperature, have a variety of carbon phase structure because of the existence of sintering pressure and temperature gradient, performing for the perfect micro-crystal of diamonds, nano-graphite and amorDhous carbon.
