Plasma spherical tungsten powder is a kind of spherical tungsten powder prepared by high frequency induction plasma torch, which can be used for making porous tungsten parts and rocket nozzle bushing.
Application
The powder metallurgy compaction made of plasma spherical tungsten powder is very uniform during sintering process and can achieve good size control.
The rocket nozzle bushing with plasma spherical tungsten powder has good anti-fracture and corrosion resistance under thermal stress.
In plasma preparation of porous spherical tungsten powder, tungsten has a more uniform pore, are gradually replacing conventional tungsten powder, used to make porous tungsten components, such as cathode of high power pulse microwave tube, vacuum tube of barium tungsten cathode, the molten zinc, Al, Mg, Bi, Hg and other metal filter, the rocket's sweating material, catalyst or catalyst carrier, satellite positioning screw, etc.
