Nanocrystalline ceramic materials are being extensively studied today with the aim to develop hard but non-brittle materials. The nonhydrolytic sol-gel process has been employed successfully for preparing nanocrystalline TiC/C and TiN/C coatings. The following techniques were applied for the samples characterization: scanning microscopy, X-ray diffraction, microanalysis (WDS and EDS), transmission electron microscopy and electron diffraction and X - ray photoelectron spectroscopy. The bonding states and structures were investigated as functions of the carbon - titanium and nitrogen - titanium relations. The microscopic and microanalysis results suggest that the TiC and TiN are homogenously dispersed in a carbon matrix and the ratio of C:Ti>1. The TEM investigations of the TiC and TiN particles showed that they were formed with the average grain size below 100nm. The comprehensive XPS analysis of the coatings have been presented.
