Abstract

The influence of the peculiarities of operation of a consumable nickel alloy cathode in an MAP-1 ion-plasma spraying plant and its analogs operating under radiative cooling conditions is studied. A mathematical model of the cathode operation is proposed, and the temperature in the cathode wall is calculated. The cathode is under conditions of radiant heat exchange with the external environment in the presence of a movable annular heating source on its outer surface, which reciprocates at a constant speed. The calculation results are used to choose the parameters of technological processes of depositing high-temperature stock-produced coatings.
