| 英文摘要 | Nanocrystalline diamond (NCD) film is widely utilized in cutting tools due to its exceptional mechanical properties, including low surface roughness and good toughness. However, it has been limited by its lower hardness. In this study, the microwave plasma chemical vapor deposition (MPCVD) technique was used to deposit NCD films on tungsten carbide-cobalt (WC -Co) substrates with different CH 4 content. The mechanical properties of NCD films were evaluated using the nanoindentation method. It was found that the hardness of NCD films reached 84 GPa at a low CH 4 content, which is attributed to its high crystal quality, high sp 3 -C content and high compressive stress. The transmission electron microscopy (TEM) was used to examine the cross-sectional microstructure of NCD films. The NCD films with high hardness were found to have partial twinning features such as twinned boundaries (TBs) inhibited dislocation motion, resulting in increased hardness. This work improves the hardness of NCD films and is important to promote the wide application of NCD films in the field of cutting tools. |
