英文摘要	The deposition of diamond coatings is often impaired by poor adhesion on hard metal substrates. To enhance the adhesion of diamond coatings on Co-cemented tungsten carbide (WC-Co), TiB2 thin films (100 nm to 1 mu m in thickness) were deposited as interlayers by magnetron sputtering. Diamond coatings were continuously, densely and quickly deposited on the TiB2 interlayers. The adhesion of the diamond coatings evaluated by Rockwell C indentation, was enhanced by utilizing TiB2 interlayer with appropriate thickness compared to that without interlayer. The barrier function of the interlayer versus cobalt is dependent on the thickness of the TiB2 inter layer. As observed by scanning electron microscopy (SEM) combined with energy dispersive X-ray spectroscopy (EDS), the cobalt diffusion was effectively hindered by utilizing TiB2 interlayers with a thickness greater than 200 nm, whereas the strongest film adhesion was obtained for the TiB2 interlayer with thickness of ca. 200 nm. Furthermore, the thickness of the deposited diamond film was 1.7 times higher than that of the diamond film grown without TiB2 interlayer, indicating an accelerated growth Raman spectroscopy and X-ray diffraction (XRD) analyses demonstrated the existence of TiB2 and high quality of diamond films. This work indicates that thin TiB2 interlayers are promising candidates for achieving adherent diamond coated cutting tools, such as micro-drills and milling tools.
