마이크로파 플라즈마 CVD법에 의해 작성된 DLC 박막 진공속에서의 거동과 증착조건의 영향

DLC films due to their extreme properties have attracted a lot of attention. In this study, the films were prepared on High Speed Steel (SKH2) by microwave plasma assisted CVD method using CH4. Every friction test under the normal load 2,5N and sliding velocity of 20,25mm/s in high vacuum (5${\times}$10$\^$-5/ Torr). The films were analyzed with Raman spectroscopy. The films failed immediately in vacuum due to high friction. Wear volume of DLC coated disks decreased more than that of non-DLC coated disks. Also, hardness of the films is about 600HV.
