The Characteristic of Diamond Thin Films on WC-Co by RF PACVD

RF PACVD법에 의한 WC-Co에 성장된 다이아몬드 박막의 특성

We prepared diamond thin films on WC-Co substrate in $H_2-CH_4-O_2$ gas mixture using 13.56MHz RF PACVD. Scanning electron microscopy, X-ray diffraction and Raman spectroscopy were used to analyze the nature of thin film. and Rockwell test to analyze the adhesion between thin film and substrate. The good diamond quality and adhesion was appeared with cemented tungsten carbide substrate treated with oxygen plasma.
