Irradiation of Ti[N(CH 3 ) 2 ] 4 by the 1.064‐μm line of a pulsed Nd: YAG laser in the presence of TiO 2 , Al 2 O 3 , or Si 3 N 4 particles has been found to form amorphous deposits on the oxide particles. The resulting materials can be processed into TiN/TiO 2 , TiN/Al 2 O 3 , or TiN/Si 3 N 4 composites with the TiN component on the surface of the particles. The powders have been characterized by Raman spectroscopy and X‐ray powder diffraction studies. The surface analysis of the composites by X‐ray photoelectron spectroscopy and high‐resolution electron microscopy is presented.
