Abstract In order to produce Mo Si intermetallic compounds pure molybdenum and siliconepowders were mechanically milled Furthermore X ray diffraction heat treatment and meanparticle size calculation the optimum of milling time was obtained which it is 15 hour for thissystem Due to small particle size which is not suitable for thermal spray processing chemical agglomeration with carboxy methyl cellulose CMC was carried out Differentconcentrations of CMC was examined and 1wt CMC chosen as the best concentration Byutilizing atmospheric plasma spray processing feed stock powders sprayed on a coppersubstrate Results indicate that during thermal spray process MoSi2 Mo5Si3 SiO2 and MoO2were synthesized Tribological behavior evolution of coating was evaluated
