VIGA Process Working Principle
The metal & metal alloy are melted under vacuum conditions with protective gas. The metal liquid flows through thermal insulating crucible and diversion tube to the atomizing chamber. Meanwhile, the liquid will be atomized & cracked into small droplets by high pressure air flow via tight coupling nozzle. The droplet will solidify into spherical or semi-spherical particles during falling down.
This equipment is used for producing superalloy powders of 50-500 micron which are applied as materials for high temperature rotating components of turbine disc of aero engine, compressor disc, etc and for energy conversion devices of aerospace craft, nuclear reactor, petrochemical equipment, and coal conversion etc.
TC4 Powders SEM, PREP(left) and GA(right)
It used for producing high melting and alive metal powders, such as nickel-based or Ti-based alloy powder. It’s also suitable for producing various alloy powders, such as steel, cobalt, chromium, etc.
The feedstock doesn’t contact with refractory materials during melting and atomizing processes, which eliminates non-metallic inclusions of pollution sources and produces clean powders.
The atomized powders is of regular shape, high sphericity, bright surface and good fluidity.
There’s no satellite phenomenon and hollow powder.
Powder particle distribution.
Manufacturing numerous special alloy powders as fast solidification overcomes aliquation.
