Metal powder is the basic and key material of metal 3D printing process. Avant has been committed to the research and development of high quality 3D printing alloy powder materials. It is reported that avant is developing a new generation of plasma atomization (PA) powder making technology, which will introduce a new super high purity spherical titanium alloy powder product ama-ti6al4v to users around the world.
PA technology is the world's 3 d printing technology of titanium powder, one of the hot topics in the study of plasma jet of high heat input and it is based on steady flow atomization characteristics, can effectively control the rate of the hollow powder, powder powder high sphericity and showed "like water" liquidity, especially adapted to the metal 3 d printing process.
Plasma atomization (PA) -- "all-excellent" in the field of spherical metal powder preparation technology.
PA technology using titanium silk as raw materials, the use of plasma jet will be silk material melt, then ultrafine impact dispersion atomized into droplets, flying in the spray tower deposits, with heat exchange cooling argon going into the spray tower, and then cooling solidification into superfine powder, as shown.
Compared with plasma rotating electrode powder preparation (PREP), the titanium powder produced by PA ensures a high sphericity while the powder is finer and the fine powder yield is better. Compared with VIGA, EIGA and other aerosol fogging methods, PA ensures the yield of fine powder, and the powder has a higher sphericity, and there is almost no hollow powder in fine powder. Compared with plasma spheroidization, PA process is more efficient. The comprehensive advantages of PA technology can be said to be the "total excellence" in the field of spherical metal powder preparation technology.
