金刚石和立方氮化硼（cBN）作为传统的超硬材料已经获得了广泛的工业应用，但两者都具有固有的局限性。金刚石由于化学惰性差，不适合高速切削黑色金属材料，而cBN的硬度只有金刚石的一半左右。由于它们在结构晶格中的亲和力和共价键合特性，金刚石和cBN可以形成合金，从而有可能填补性能差距。然而，这一想法从未得到证实，因为在以前的研究中获得的样本太小，无法测试其实际性能。在这里，我们报告的合成和表征的透明散装金刚石-cBN合金压坯的直径（3毫米）是足够大的，他们被加工成切削工具。测试结果表明，金刚石-立方氮化硼合金具有比多晶金刚石上级的化学惰性和比单晶立方氮化硼高的硬度。对淬硬钢和花岗岩的高速切削试验表明，金刚石-立方氮化硼合金确实是一种通用的切削材料。(C)2015 AIP Publishing LLC.
Diamond and cubic boron nitride (cBN) as conventional superhard materials have found widespread industrial applications, but both have inherent limitations. Diamond is not suitable for high-speed cutting of ferrous materials due to its poor chemical inertness, while cBN is only about half as hard as diamond. Because of their affinity in structural lattices and covalent bonding character, diamond and cBN could form alloys that can potentially fill the performance gap. However, the idea has never been demonstrated because samples obtained in the previous studies were too small to be tested for their practical performance. Here, we report the synthesis and characterization of transparent bulk diamond-cBN alloy compacts whose diameters (3 mm) are sufficiently large for them to be processed into cutting tools. The testing results show that the diamond-cBN alloy has superior chemical inertness over polycrystalline diamond and higher hardness than single crystal cBN. High-speed cutting tests on hardened steel and granite suggest that diamond-cBN alloy is indeed a universal cutting material. (C) 2015 AIP Publishing LLC.
