| Summary: | The influence of the deposition temperature of TiC WC quasi-binary system ion-plasma coatings (magnetron scheme) of different composition is investigated. The substantial expansion of the probable structural and substructural states under nonequilibrium conditions of receiving a material from ion-plasma fluxes is demonstrated. The composition changes from monophase (Ti, W)C to two-phase (Ti, W)C and α W2C, the structure – from the nontextured one to the texture with the axes [111], [100] or [110]. The type of the texture depends on the deposition temperature and composition. When the state on the substructural level is monophase the increase of the substrate temperature leads to the increase in the size of crystallites and microstrain reduction. Creating the second phase determines opposite effects – reduce the size of the crystallites coverage and increase microstrain. |
