UDC 621.791.927.55

An analytical solution of the problem of heat conduction 
in crystallization of a particle on a coating sprayed by an open jet 
onto a flat base (substrate) is given in a one-dimensional approximation. 
The initial temperature of the particle is equal to the melting temperature 
of its material. The coating is considered as a multilayer plate with 
a layer thickness of one crystallized scale particle; thermal resistance 
occurs between the layers and between the coating and the substrate. 
Examples of calculation of the temperatures in crystallization of 
the particle near the substrate and at a distance from it are given.
