Influence of the plasmatron anode length in the processes of powder production and coating

A computer model of the plasmatron was created, which adequately describes the plasma flow. The effect of changing the length of the anode on the speed and temperature at characteristic points of the flow is investigated. To confirm the results of the numerical experiment, a field experiment was performed. The results of the comparative analysis of the data of the computer and field experiments are in agreement. The presented results are of practical value for manufacturers and users of technological plasma installation for improving the equipment used in the processes of obtaining metal powders and applying protective coatings and can be used to predict the parameters of a plasma flow. Recommendations for choosing the length of the anode are presented.
