The relatively not high metal of the fusing points such as nickel-base alloy can not just carry out more dystectic tungsten, molybdenum, tantalum, niobium Base Metal and alloy
It melts and powder processed.In addition it will appear electrode not during using induction melting aerosolization technology smelting metal bar or silk material
It is completely melt and falls into diversion pipe, cause to block, thus it is a technological difficulties of EIGA to keep the continuous-stable of liquid stream.Separately
Outside, the drop after induction melting is detached from high-temperature region and is atomized immediately, thus the degree of superheat of the molten drop after general fusing compared with
It is low, there is no enough temperature and times to ensure that drop shrinks balling-up under surface tension effects during temperature reconstruction,
Therefore the sphericity of powder is bad, also will produce hollow ball.
Radio frequency plasma nodularization method (RF), generally use radio frequency plasma torch heat raw material, have other methods without
The advantages that plasma temperature of method analogy is high, electrodeless pollution；Usually using metal powder as raw material, by plasma high temperature melting
After change, drop shrinks balling-up under surface tension effects again, and then solidifies, and can obtain the good spherical powder of sphericity.It lacks
Point is that powder raw material purity, granularity are limited by raw material itself, and powder is very short by the time of plasma high-temperature region, powder output
And Oxygen potential is relatively low.
