Preparation of Composite Particles by Pulsed Nd-YAG Laser Decomposition of [(CH3)2N]4Ti to TiN-Coat TiO2, Al2O3, or Si3N4 Powders

Preparation of Composite Particles by Pulsed Nd-YAG Laser Decomposition of [(CH3)2N]4Ti to TiN-Coat TiO2, Al2O3, or Si3N4 Powders

Irradiation of Ti[N(CH3)2]4 by the 1.064‐μm line of a pulsed Nd: YAG laser in the presence of TiO2, Al2O3, or Si3N4 particles has been found to form amorphous deposits on the oxide particles. The resulting materials can be processed into TiN/TiO2, TiN/Al2O3, or TiN/Si3N4 composites with the TiN comp...

Zusammenfassung:Irradiation of Ti[N(CH3)2]4 by the 1.064‐μm line of a pulsed Nd: YAG laser in the presence of TiO2, Al2O3, or Si3N4 particles has been found to form amorphous deposits on the oxide particles. The resulting materials can be processed into TiN/TiO2, TiN/Al2O3, or TiN/Si3N4 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.
