| 摘 要： | 聚晶金刚石(polycrystalline diamond，PCD)是以金刚石为骨架材料，以结合剂为黏结材料，在高压高温条件下烧结而成的复合材料。因其拥有优异的硬度与良好的耐磨性能，被广泛应用于刀具、拉丝模等领域。本文概述了PCD的结合剂种类、制备方法、影响性能的因素，分别介绍了金属型、陶瓷型和金属-陶瓷型等3种不同结合剂PCD的结合机理及优缺点，并对比分析了不同制备方法的差异。其中金属-陶瓷型PCD因综合了金属与陶瓷的优良性能而成为一个重要的研究方向。

| Abstract: | Polycrystalline diamond (PCD) is sintered under high pressure and high temperature conditions with diamond as the skeleton material and binder as the bonding material. Due to its excellent hardness and good wear resistance, PCD is widely used in cutting tools, drawing die and other fields. In this paper, the binder types, the preparation methods and the factors affecting PCD performance were summarized. The binding mechanism, the advantages and the disadvantages of three types of PCD, namely metal binder, ceramic binder and cermet binder, were introduced respectively. The differences between the preparation methods were compared. Cermet PCD, which combined the good performance of metal PCD and ceramic PCD, had become an important research direction. |
