Loss of carbon during plasma-spraying of clad carbide powders

Composition of particles upon atomization of unclad and clad powders is studied. It is estabished that the losses of carbon upon atomization of unclad particles are different for different carbides and increase in the sequence Cr3C2-TiC-WC. Upon atomization of clad powders, we observed the highest carbon losses for the particles of tungsten carbide, somewhat smaller losses for titanium carbide, and almost negligible losses for chromium carbide.
