Morphological Characterization of Combustion Deposited Diamond Crystals and Films

Single crystals and polycrystalline diamond films of several thicknesses were deposited using oxygen/acetylene combustion flame technique. The substrate used was pure polycrystalline molybdenum subjected to mechanical polishing. Quality and microstructural characteristic of diamond produced were investigated using X-Ray diffraction, Raman Spectroscopy, Scanning and Transmission Electron Microscopy. Results obtained revealed that a good quality single and polycrystalline diamond could be produced. However, a combination of various defects such as twins, dislocations and stacking faults are always present.
