Paper Title:
Selected Interlayer of Diamond Deposition on γ-TiAl Intermetallic Compounds Prepared by Microwave-Plasma Assisted CVD
  Abstract

Several diamond coatings were performed on -TiAl substrates by a microwave-plasma assisted CVD, which were made directly to the substrate and indirectly to the TiC, Ti5Si3, Al2O3+TiO2 and Si layers on the substrate. The direct coatings suffered from severe delamination and cracks. The deposited layers on TiC and Ti5Si3 layers partially delaminated, while those on Al2O3+TiO2 and Si layers adhered well without delamination. All the diamond films deposited were characterized using scanning electron microscopy, Raman spectroscopy, and X-ray diffraction. Raman spectra showed that poly- and nano-crystalline diamond films were obtained for the coatings of -TiAl.
