Under action of different dc negative-bias voltages on samples incorporating with silicon, a series of Si-B-N composite films were synthesized on steel 1045 using RF-PECVD technique (radio-frequency plasma enhanced chemical vapor deposition), and the surface analysis of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and etc. were followed. The experimental results showed: Si-B-N composite films had an obvious mixture phase of c-BN and h-BN crystal at a certain dc negative bias, and the film's mechanical performances including micro-hardness and adhesion were improved. Moreover, bias effect on deposition performance of Si-B-N composite film has been systematically investigated, and silicon introduction was found to be necessary for the growth of Si-B-N film and the improvement of adhesion. © 2004 Elsevier B.V.
