Elaboration du carbure et du nitrure de titane par ds procédés chimiques et physiques en phase vapeur : caractérisation de la microstructure

Abstract : Titanium carbide and titanium nitride were obtained by CVD and PVD techniques. These processes allowed the elaboration of a thick ceramic coating for protecting a tungsten metallic device. The influence of several experimental parameters, proper at each deposition technique, has been studied on the nucleation, the microstructure and the preferred orientation of the coatings, considering the interaction with the substrate. Residual stresses were estimated by sin2 ψ method and a correlation with the microstructure was done in order to explain the cracking behaviour of different coatings.
