摘要

Diamond growth on polycrystalline Ti3SiC2 was investigated using microwave plasma chemical vapour deposition (MPCVD) under typical microcrystalline diamond growth conditions. Scanning electron microscopy (SEM), atomic force microscopy (AFM), Raman spectroscopy and synchrotron near edge extended x-ray absorption fine structure spectroscopy (NEXAFS) were used to characterize the synthesized films. A diamond nucleation density of 1011 cm(-2) has been achieved and consequently, dense nanocrystalline diamond (NCD) thin films with an average grain size of approximately 30 nm and a film growth rate of approximately 2 mu m h(-1) were synthesized. The NEXAFS spectra of the NCD films exhibit clear spectral characteristics of natural diamond with a weak peak of sp(2) carbon. Cross-sectional SEM images show that the NCD films have an equiaxed grain structure and a dense film/substrate interface.
