ANALYSIS OF POWDER USAGE IN A PLASMA SPRAYING PROCESS

摘要

A mathematical model for calculation of a degree of usage a layer material in a process of its spraying on a subside body of an arbitrary shape in a plasmothron has been described in the paper. The material has been introduced into a plasmothron in a form of a powder. Calculations have been based on a balance of mass of the fed powder in the process. An account has been taken for a coefficient of reflection. Its value has been related both to a design of a plasmothron and to properties of the powder.
