The heat flux to a metal particle in the plasma of a short 
argon arc of atmospheric pressure in depositing metallurgical coatings 
has been calculated. The limiting approximations of a continuum and 
free-molecular flow yield comparable results (about 6*108W/m2. 
The radiant-flux density has been evaluated. It has been shown 
that the heating of macroparticles is determined mainly by 
the conductive mechanism of energy transfer.
