In recent years, the CVD for synthetic diamonds has been constantly improved. Meanwhile, a variety of new deposition methods, with more than 10 different methods, have been developed, each excite the method in different ways. Spitsyn et al [55] classified the CVD process into four different types, as shown in Fig. 9. According to thermal, chemical, electrical and electromagnetic techniques to further decompose […]

Single-crystal diamond tools were earlier widely employed for the machining of non-ferrous metals, such as aluminum, copper, and gold. When used for machining these materials, it is attainable to achieve surface roughness in the nanometer range, superior to that of all existing tools. Severe tool wear can only be detected on cutting distances of the order of […]

Single-crystal diamond is a highly costly material, generally priced at approximately four times that of PCD. Inexpensive PCD tools possess exceptional properties such as ultra-hardness (8000 HV≈78.4 GPa), high wear resistance, and excellent thermal conductivity (560·W/m·K) [245], making it an ideal tool material for machining difficult-to-cut materials. PCD is a composite material made by mixing selected […]

Owing to the high hardness and strong wear resistance of diamond, it is highly suitable to be a tool material. Therefore, synthetic and natural diamond is widely employed as a cutting tool in ultra-precision machining and nanoindentation [8]. In fact, the wear resistance of diamond cutting tool is largely determined by crystal facets and orientations. […]
