Abstract

Large-area cubic boron nitride/nanocrystalline diamond (cBN/ND) composite films were deposited on silicon substrates using plasma-assisted (PA) CVD processes, and a systematic study of their mechanical properties was carried out. The direct growth of cBN on ND without an amorphous and turbostratic BN interfacial layer dramatically improves the adherence of cBN films. Because of the strengthened adhesion and improved mechanical properties due to the layered structure and the smooth surface, the composite films could be used in mechanical and some device applications. © 2006 WILEY-VCH Verlag GmbH & Co.
