当前,在工业生产中掌握了人造多晶金刚石新型工具材料的使用,这种材料同天然单晶金刚石相比,具有许多优点。首先,由于制造这种多晶金刚石的方法很多,这样就能够通过改变多晶金刚石的物理机械性能来满足随着其使用范围的不同而改变工具的各种使用性能。不管多晶体的制造方法如何,但它都是由大量细颗粒金刚石同石墨、金属催化剂,以及金属的碳化物混合而制成的。由于多晶金刚石的晶粒在各个方向具有相同的性质(各向同性),并且没有解理面,因而,显著地提高了它的机械性能。首先,提高了它的强度和冲击韧性。多晶金刚石按其组成成分和制造方法分为 At present, the use of a new type of artificial polycrystalline diamond tool material is mastered in industrial production, which has many advantages over natural single crystal diamond. First of all, since there are many ways to manufacture such polycrystalline diamond, it is possible to change various usability properties of the tool depending on its range of use by changing the physical-mechanical properties of the polycrystalline diamond. Regardless of how polycrystalline is made, it is made from a combination of a large amount of fine-grained diamond with graphite, a metal catalyst, and a metal carbide. Since the grains of polycrystalline diamond have the same properties (isotropic) in all directions and have no cleavage plane, their mechanical properties are significantly improved. First, it increases its strength and impact toughness. Polycrystalline diamond is divided into its components and manufacturing methods
