Zirconium dioxide refractory erosion in an ionized combustion product flow

Abstract

Erosion is considered for zirconium refractories in a hot gas flow. Additional ionization of the flow with 1% of atomic potassium in terms of the mass of combustion products increases the wear, and also causes diffusion in the structure. Consequently, local accumulations of carbon occur in the intergranular zones of a coarse-grained specimen.
