Nanocrystalline carbides, nitrides and carbonitrides are being studied today with the aim to develop hard but non-brittle materials. Carbides and nitrides are materials that have desirable properties for a variety of applications. Their key properties are high hardness and strength along with resistance to heat, corrosion and wear.The nonhydrolytic sol-gel process has been employed successfully for the preparation of the nanocomposites TiC/C and TiN/C in form powders. In this study, the results about characterization of nanostructured TiC/C and TiN/C composites elaborated by sol-gel method. The TiC and TiN crystallite sizes and lattice parameters have been determined through X-ray diffraction method by measuring the full width at half maximum (F.W.H.M.) and the intensities of the TiC or TiN powder peaks.
The obtained the TiC/C and TiN/C powders were additionally characterized by the microanalysis (wavelength dispersive and energy dispersive spectroscopies) using an IBEX System Noran Instruments and an Oxford ISIS 300, scanning electron microscopy (JEOL JSM 6100), X-ray diffraction (PHILIPS X’PERT), transmission electron microscopy and electron diffraction (JEOL JEM 1200EX).
