Numerical Simulation of Heating Dynamics of Powder Materials in Technological Micro-plasmatron

摘要

A new trend in technology of the gas-thermal coating is discussed - the microplazma coating which allows to overcome some problems inherent to the traditional plasma coating. A possibility to implement coating by plazmatrons with a power up to 2-2.5 kWt is shown with entering the powder material at the initial part of arc. A simplified mathematical simulation of dynamics of heating the powder materials in the technological micro-plazmatron is presented allowing to evaluate technological modes of various materials coating. Numerical results for the given simulation are discussed.
