Abstract

The modeling of powders melting in a plasma jet has received increasing attention as the plasma spraying is being developed to produce high density, high performance materials. These models are being used to predict process capability for melting powders and to develop plasma processing parameters for complete particle melting. Most models assume splherical powder particles which heat and melt uniformly during their travel in the plasma jet. The results of this research indicate this assumption may be invalid. Several experiments conducted to evaluate the melting behavior of nickel and nickel alloy powders (Ni,Ni2OCu, Ni2OCr, Ni5O Cr, Rene'80) are presented.
