| 摘 要： | 为了在高速钢刀具上制备先进的氮化碳超硬涂层，采用DC反应磁控溅射和电弧离子镀相结合的方法在高速钢上沉积氮化碳一氮化钛复合膜，经X射线衍射分析，复合膜中存在α-C3N4和β－C3N4两种硬度相。复合膜的显微硬度（HK）为50．5－54．1GPa，用划痕试验测量它与高速钢基体的附着力，测得临界载荷Lc=40-80N，多种刀具试用证实，该涂层具有很高的耐磨性，与未涂层和镀TiN的刀具相比，大幅度提高了刀具的耐用度。

| Abstract: | For depositing advanced superhard coating film of Carbon Nitride onto high speed steel tool , by combination of DC reaction magretron sputtering with multiple arc plating, the superhard coating is deposited onto high speed steel, and a compound thin film exists in the form of hard crystalline phase using X ray diffraction (XRD) analysis. The microhardness Hv of the compound film is of 50. 5-54- 1GPa. The adhersive force of super-hard coating film with high speed steel base is of L = 40 -80N, by scratch test to measure the critical load, Many kinds of tool proves that coating has a very high wearabil ity, the tool life is great improved,as compared with TiN coated cutting tools and uncoated tools. |
