Vorobev, A., Zikanov, O. and Mohanty, P. (2008) A co-condensation model for in-flight synthesis of metal-carbide nanoparticles in thermal plasma jet. Journal of Thermal Spray Technology, 17, (5-6), 956-965. (doi:10.1007/s11666-008-9240-y).
We present a theoretical analysis of the formation, growth, and transport of two-component nanoparticles in thermal plasma jet. The approach of the aerosol science and the idea of multicomponent co-condensation are employed for the analysis. The processes of homogeneous nucleation, heterogeneous growth, and coagulations due to Brownian collisions are considered in combination with the convective and diffusive transport of particles and the reacting gases within an axisymmetric domain. As a particular example, the authors study multicomponent co-condensation of metal-carbide nanoparticles from various precursors in a DC plasma gun operating in an argon atmosphere.
