本文采用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-氮化钛复合膜
经X射线衍射分析
复合膜中存在a-C3N4和b-C3N4的硬质相。复合膜的显微硬度 HK=50.5—54.1GPa
它与高速钢基体的附着力
用划痕试验测得临界载荷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。
By combination of DC reaction magnetron sputtering with multiple arc-plating
the superhard coating is deposited onto HSS. X-ray diffraction (XRD) shows that the compound film exists in the form of hard crystalline phase. Microhardness HV of the compound film is 50.5—54.1GPa
and adhesive force to the HSS base (critical load) measured
by scratch test
to be 40—80N. It is proved that the coating has a very high wear resistance and the cutting life of the TiN coated cutting tools is great improved.
