Abstract
Mathematical model has been developed for calculation of dynamics of heating of composite powder particles in a plasma jet, allowing for the heat released as a result of chemical reaction between the initial components of powder materials. Software has been developed to implement the model on a computer. Numerical analysis has been conducted for peculiarities of heating and movement of composite particles Ni--Al in the plasma jet, allowing for the heat released in the bulk of the particles through the exothermic reaction of formation of an intermetallic compound
Keywords: plasma spraying, composite powder, heating of particles, exothermic reaction, intermetallic, mathematical model, software
