 Production Method of 3D Printing Alloy Spherical Cobalt Powder

Gas Atomization

1. Raw Material Preparation: Select high-purity cobalt and other alloying elements according to the desired alloy composition. For example, if making a Co – Cr – Mo alloy powder, accurate amounts of cobalt, chromium, and molybdenum are weighed.
2. Melting: The raw materials are placed in a high-temperature melting furnace, such as an induction furnace. The stove is usually operated under an inert gas atmosphere (e.g., argon) to prevent oxidation of the metals. The temperature is raised above the melting point of the alloy, typically around 1400 – 1600 °C for cobalt-based alloys, to obtain a homogeneous molten metal.
3. Atomization: The molten metal is poured through a small nozzle at a controlled rate. High-pressure inert gas (such as argon) is then sprayed onto the molten metal stream. The high-velocity gas breaks the stream into tiny droplets. Due to surface tension, these droplets tend to form spherical shapes.
4. Solidification and Collection: The droplets solidify rapidly as they cool in the gas-filled chamber. The solidified spherical powder is collected at the bottom of the chamber. Then, it undergoes further processing, such as sieving, to obtain the desired particle size distribution.

Plasma Atomization

1. Material Feed: Cobalt or its alloy in the form of a rod or wire is fed into a plasma torch.
2. Plasma Melting and Atomization: The plasma torch generates a high-temperature plasma arc (temperatures can reach tens of thousands of degrees Celsius). The high-energy plasma melts the fed material. The molten metal is then atomized by the high-velocity plasma jet, breaking it into fine droplets.
3. Cooling and Collection: Similar to gas atomization, the droplets cool and solidify in a controlled environment to form a spherical powder. The powder is collected and may be post-processed to meet specific requirements.

Chemical Reduction Method

1. Solution Preparation: Cobalt salts (such as cobalt chloride or cobalt nitrate) are dissolved in a suitable solvent to form a homogeneous solution. Other alloying element salts can also be added if making an alloy powder.
2. Reduction Reaction: A reducing agent, such as sodium borohydride or hydrazine, is added to the solution. The reducing agent reacts with the cobalt ions in the solution, reducing them to metallic cobalt. Under proper reaction conditions, the cobalt atoms aggregate to form spherical particles.
3. Separation and Purification: The formed cobalt powder is separated from the solution through filtration or centrifugation. It is then washed and dried to remove impurities and obtain pure spherical cobalt powder. However, this method may have limitations in achieving large-scale production and high-purity powder compared to the physical atomization methods.
