Description	Wear-resistant and heat-resistant coatings as well as free-standing parts of tungsten disilicide were manufactured by plasma spraying. Tungsten disilicide powder was processed by water stabilized plasma, generated by IPPs WSP plasma torch, which can reach exit temperatures up to 28000 K. Oxidation of the molten silicide was prevented by an argon protective atmosphere and by %22auto-shrouding%22 effect. Their mechanical and oxidation behavior was compared with samples prepared by powder metallurgy techniques, sintered in the ASEA apparatus and also in the HP-type apparatus. Heat-resistant coatings exhibited high resistance against oxidation similarly to MoSi2 produced by the same way. Tungsten disilicide feedstock was prepared by direct heating of the powder mixture of tungsten and silicon at 1350-1400 C and secondly by plasma spheoidization of granules (20-63 microns in size) of powder mixture of tungsten and silicon with 3% of a polyvinylalcohol binder by the technique known as freeze granulation.
