Titanium has the advantages of low density, high specific strength and good corrosion resistance, and is widely used in aerospace and other fields. With the continuous development of the application of spherical titanium powder such as powder metallurgy and 3D printing technology, the demand for spherical titanium powder has also increased rapidly. hotspot of technology research. At present, the preparation methods of spherical titanium powder mainly include sponge titanium mechanical pulverization method, atomization method and plasma rotating electrode method.
Among them, the mechanical pulverization method refers to a method of pulverizing metals or alloys into powder by simple mechanical action. Due to the toughness of titanium, the shape of the powder obtained by pulverization by this method is irregular, and the pollution during the pulverization process makes the purity of titanium It does not meet the production requirements; the atomization method is a method of using high-speed airflow to impact and crush the molten metal flow and rapidly cooling it to form metal powder. During the atomization process, the molten metal is volatile, and the obtained powder Most of them are satellite spheres or hollow particles.
The plasma rotating electrode method is to make a metal or alloy into a consumable electrode, and the end face of the electrode is heated by an arc to melt into a liquid, and the liquid is thrown and pulverized into fine droplets by the centrifugal force of the high-speed rotation of the electrode, and finally condensed into a powder. Method, the powder prepared by this method has good sphericity and few hollow particles and planetary particles, but this method also has certain defects. The particle size of spherical titanium powder prepared by this method is mostly concentrated in the range of 100 microns, 50 microns. The yield of spherical titanium powder on the left and right is low. These methods all use dense titanium such as sponge titanium or titanium ingots (titanium rods) as raw materials, and the obtained spherical titanium powder has a larger particle size and a higher production cost.

Ningbo Chuangrun New Materials Co., Ltd.  (CRNMC) was established in June 2012 and has 4 production bases.
