Principle of pulverizing
3D printing metal powder is the most important link in 3D printing industry chain of the metal parts , and it is also the greatest value. The rotating electrode method is used to prepare spherical titanium and titanium alloy powder for 3D printing, which solves the problems of difficult and costly preparation of ultra-fine titanium and titanium alloy powder in prior art. The specific methods are as follows:
The titanium rod or titanium alloy rod is put into the rotating atomizer for arc melting, the vacuum degree of the control device is 0.6Pa, and under the protection of inert gas, the DC plasma torch is opened to melt the titanium rod or titanium alloy rod into liquid drops. By controlling the rotation speed of the rotating electrode, the droplets are broken into fine particles by centrifugal force, so as to obtain the spherical titanium powder or titanium alloy powder for 3D printing.
The method combines the arc melting system and the rotating electrode system, and has the characteristics of high production efficiency and low energy consumption. The product has good sphericity, low oxygen content and good fluidity, making it an ideal raw material for 3D printing.
Application field
Laser 3D printing technology has significant advantages in the direct forming of large complex titanium alloy structural parts, and shows broad application prospects especially in the development and production of aircraft equipment. With the rapid development of the industrial application of 3D printing of high-performance titanium alloy structural parts, the market demand for raw material powder has also increased significantly.
TA15 3D electrode rod/powder rod, as a raw material for high-performance titanium alloy powder, is widely used in aerospace, medical equipment, automobile manufacturing and other fields, which has promoted the further development of 3D printing technology.
