Description
Atomization pulverizing method is a powder production by rapidly moving fluid (atomizing medium) impacting or otherwise breaking metal or alloy liquids into fine droplets, followed by condensation into solid powders.
Most of the water atomized powder particles are irregular in shape,
with high oxygen content (higher than 600×10), and must be
annealed, but they have good compressibility and can be
cold-pressed and then sintered into mechanical parts. The
above-mentioned atomization pulverizing method is easy for
large-scale industrial production, but because the alloy liquid is
in contact with the slag body and the refractory crucible,
non-metallic inclusions are inevitably brought into the powder.
Therefore, according to the principle of electroslag remelting
(ESR), the Swedish Soderfors powder company first changed the
tundish with a capacity of 7t to an electroslag heating (ESH)
device, and atomized the non-ferrous metals in the high-speed steel
powder by nitrogen atomization. The amount of metal inclusions is
reduced to 1/10 of the original amount, which increases the
flexural strength of ASP powder high-speed steel from 3500MPa to
over 4000MPa.
The measure that can completely and effectively avoid oxide
inclusion pollution is to use a "single-flow" atomization powder
method, such as a rotating electrode atomization powder method (see
rotating electrode powder method). In addition, there is a vacuum
dissolved gas atomization method that can also produce high-purity
spherical powder. The principle is: when the alloy liquid
supersaturated by gas under air pressure is suddenly exposed to
vacuum, the dissolved gas will escape and expand, causing the alloy
liquid to atomize and then condense into powder. For base alloys
such as nickel, copper, cobalt, iron, and aluminum, the method of
dissolving hydrogen can be used to achieve vacuum solution gas
atomization.
