Nanostructured silicon carbide films have been deposited on molybdenum substrates by hypersonic plasma particle deposition. In this process a thermal plasma with injected reactants (SiCl4 and CH4) is expanded through a nozzle leading to the nucleation of ultrafine particles. Particles entrained in the supersonic flow are then inertially deposited in vacuum onto a temperature-controlled

16/7/2017· The YSZ-SiC composites also exhibited high flexural strength (as high as 1142 MPa) and high fracture toughness (up to approximately 8 MPa-m 1/2), which are similar to those of the fine-grained YSZ. Such a coination of mechanical properties was attributed to the fine microstructure with a distinct feature consisting of almost continuous network of YSZ phase around SiC particles.
