Thermal spray feeder powder of WC-Co was prepared by H2 reduction of the perform by spray drying granulating of ball milled mixture started from water soluble cobalt acetate,WC powder,pure water,solid carbon powder and liquid organic carbon.It was shown that during spraying drying granulating process,particle size range is from 10μm to 80μm,with mean particle size around 35μm,when inlet air temperature is 260℃,outlet temperature is 140 ℃and when revolving speed of the spray drying nozzle is 10000r/min.It was also shown that during H2 reduction process,when powder was heated up to 1250 ℃,which is near the eutectic temperature,liquid phase was formed in the powder,leading to alloy of elements,shrink of the particle and increase of bulk density.Powder obtained had particle size from 10μm to 50μm,with mean particle size around 25μm.SEM shown that cobalt phase was uniformly distributed in the particle.
