Metal powder is the primary and critical material of the metal 3D printing process, and AVIC has been committed to the research and development of high-quality 3D printing alloy powder materials. It is reported that KMPASS is developing a new generation of plasma atomization (PA) powder technology and will launch a new ultra-high purity spherical titanium alloy powder product Ti6Al4V powder to users around the world.
PA technology is one of the hotspots of global 3D printing titanium powder technology research. The high thermal energy input of plasma jet and steady flow atomization characteristics can effectively control the powder's hollow powder rate. The powder has high sphericity, showing "like water "The fluidity is especially suitable for the metal 3D printing process.
Plasma Atomization (PA)-the "full eugenics" in the field of spherical metal powder preparation technology
PA technology uses titanium wire as raw material, uses plasma jet to melt the wire, and then impacts, disperses and atomizes into ultra-fine droplets, deposited on the fly in the atomization tower, and exchange heat with the cooling argon gas passed into the atomization tower. Then it cools and solidifies into ultra-fine powder, as shown in the figure.
Compared with the plasma rotating electrode powder technology (PREP), the titanium powder produced by the PA technology guarantees high sphericity, while the powder is more delicate and the acceptable powder yield is excellent; compared with the gas atomization methods such as VIGA and EIGA, PA While ensuring the creation of fine powder, the sphericity of the powder is higher. There is almost no hollow powder in the fine powder. Compared with the plasma spheroidization method, the PA process has higher production efficiency. PA technology has many advantages, which can be said to be the "full eugenics" in the field of spherical metal powder preparation technology.
"Three Highs" performance is worth looking forward to
The titanium wire used in the PA process will not touch the reactor wall, such as ceramics, during the melting process, which reduces the risk of inclusions. Simultaneously, the prepared powder has almost no hollow powder, ensuring the powder's "high purity and low hollow rate".
PA uses hot atomizing gas instead of cold atomizing gas to prevent particles from rapidly cooling and gathering into irregular shapes. The powder produced has the characteristics of "high sphericity".
PA technology produces very few powder satellite powders and has high sphericity. AMC-Ti6Al4V titanium alloy powder has the characteristics of "high fluidity", and the Hall flow rate is 30.8s/50g, which genuinely realizes "like water" flow.
Only by focusing can you be professional. From EIGA technology to PA technology, from imitation breakthrough to technological leadership, from solving the problem of "whether or not" to batch standardized preparation, KMPASS is looking for the breakthrough of "3D printing spherical powder" and continuously launches the charge, Challenge to new heights, to produce the world's best quality 3D printing powder products, to make 3D printing design materials freer, printing performance more stable, printing costs more advantageous, and create more value with global users!
