THE INVESTIGATION OF THE TEMPERATURE FIELD IN THE THICKNESS OF THE BASE FOOD INDUSTRY MATERIALS SPRAYED IN A PLASMA JET

Abstract

This article presents the temperature field distribution outside and inside of the base material and the surface heating of the base material to the melting temperature. The high adhesion of the base material to the coating formed by plasma spraying is obtained in the case of a re-melting and subsequent crystallization of the superficial layers. Interaction of the molten particle with the re-melted surface of the base material ensures the high quality of the coatings. By suggesting values of the melting depth of the superficial layer of the base material, we determine the spent time under the action of the plasma jet.
