Numerical Calculation of the Arc-Sprayed Particles’ Temperature in Transient Thermal Field

The physical and mechanical properties of the coatings produced by electric arc thermal spraying are closely related to velocity temperature particles that interact with substrate surface. Knowing variation sprayed allows establishing their aggregation state, respectively determining distance, so state at impact moment is predominantly liquid. Obviously, when particle passes through spray cone, it cools continuously due low variable entrainment gas. This paper aims determine analytically behavior entrained gas jet formed in an arc, depending on temperature, existing along cone. In this sense, modeling finite elements, using ANSYS program, inside was determined, a mathematical model carried out based balance equations, profile determined. demonstrates suddenly increases solidification then melting temperature—due latent heat solidification, after which decreases 300 K.
