2. Grade 5 titanium alloy rod for 3D printing powder making 3D printing metal powder is an important link in the 3D printing industry chain of metal parts and also the greatest value. In addition to good plasticity, 3D printing metal powder must also meet the requirements of fine powder particle size, narrow particle size distribution, high sphericity, good fluidity and high bulk density. In the industrial world, the most widely used fields are metal products with high added value, such as titanium alloys and titanium, which are mainly used in medical and aerospace fields.
3. Grade 5 titanium alloy rod for 3D printing powder making The main process for preparing spherical titanium powder is atomization. The atomization method is expensive because it consumes a large amount of inert gas. The method of preparing spherical titanium and titanium alloy powder for 3D printing by rotating electrodes solves the technical problems of the difficulty and high cost of preparing ultrafine titanium and titanium alloy powder in the prior art. It is to put a titanium rod or a titanium alloy rod into an arc melting rotary atomization device, control the vacuum degree of the device to 0.6Pa and under the protection of inert gas, turn on the DC plasma torch to melt the titanium rod or titanium alloy rod into droplets; control the speed of the rotating electrode, and use centrifugal force to break the droplets into fine particles to obtain spherical titanium powder or titanium alloy powder for 3D printing. This method combines the arc melting system with the rotating electrode system. The production efficiency of spherical titanium and titanium alloy powder is high and the energy consumption is low. The obtained product has good sphericity, low oxygen content and good fluidity, and is a good raw material for 3D printing.
The process of making powdered titanium rods involves multiple steps, including raw material preparation, powder preparation, molding and post-processing. First, we need to select the right titanium raw material, usually sponge titanium or titanium alloy fragments with high purity. Then the bulk raw material is made into powder by methods such as gas atomization, rotating electrode process (RDP) or plasma rotating electrode process (PREP). Gas atomization is a common method in the powder preparation process. This method sprays titanium in a high-speed gas flow in a molten state, and cools and solidifies during the spraying process to eventually form fine particles. The size and shape of these particles are affected by many factors such as the design of the nozzle, the speed and temperature of the gas flow. Subsequently, the powder is screened to remove particles that are too large or too small to ensure uniformity and stability in the subsequent molding process. Next is the powder metallurgy forming step, in which the titanium powder is placed in a steel mold and sintered at high temperature and a certain pressure to form the so-called "green body". This step is crucial to the performance of the final product, because at this stage, the bonding between the powder particles will determine the microstructure and mechanical properties of the material. Post-processing of powdered titanium rods includes heat treatment, surface treatment, etc., aimed at improving its performance. For example, annealing can reduce the hardness of the material and improve its plasticity; surface treatment such as pickling can remove the oxide layer on the surface and improve the corrosion resistance and appearance of the material.
In terms of performance, powdered titanium rods have many advantages. They not only inherit the high strength and light weight characteristics of titanium metal itself, but also can achieve more precise control at the micro level due to the use of powder metallurgy technology. This makes powdered titanium rods particularly important in the highly demanding aerospace field, such as engine parts, structural frames, etc.
In addition, powdered titanium rods can also be used to manufacture medical devices, such as orthopedic implants. In these applications, the biocompatibility and mechanical properties of the material must meet strict standards. Powder metallurgy technology makes it possible to design and customize implants, thereby providing patients with more suitable medical solutions.
