Production Method of 3D Printing Alloy Spherical Chromium 7440 47 3 Powder

Physical Vapor Deposition (PVD)

Principle: In a high-vacuum environment, chromium metal is heated to a high temperature until it evaporates and forms chromium vapor. The chromium vapor then condenses on a cooled substrate or in the gas phase to form fine chromium powder particles. By precisely controlling the evaporation temperature, vacuum degree, and condensation conditions, spherical chromium powder can be obtained.

Plasma Atomization Method

Principle: Chromium materials are fed into a plasma torch. The high-temperature and high-energy plasma environment quickly melts the chromium. The molten chromium is then ejected from the plasma torch and atomized in a cooling medium, such as inert gas or water. The rapidly cooled droplets solidify to form spherical chromium powder.

Chemical Reduction Method

Principle: Chromium salts, such as chromium chloride or chromium nitrate, are used as raw materials. In an appropriate solvent, a reducing agent is added to reduce the chromium ions in the salt to elemental chromium. The decreased chromium atoms progressively accumulate and expand to create chromium powder fragments. By readjusting the response problems, such as the focus of catalysts, response temperature level, and response time, the morphology and bit dimension of the powder can be managed to get round chromium powder.

Mechanical Alloying Method

Principle: Chromium metal and other alloying elements (if any) are placed in a ball mill. The impact and friction of the grinding balls in the ball mill continuously deform, fracture, and weld the metal materials, finally forming alloy powder. If the process parameters are properly controlled, spherical chromium alloy powder can be obtained.

5 FAQs of 3D Printing Alloy Spherical Chromium 7440 47 3 Powder

Q1

Do parts printed with chromium powder require post-treatment?
Answer:Yes, parts printed with chromium powder usually require post-treatment to eliminate residual stress, improve surface quality, or improve performance. Post-treatment may include heat treatment, surface polishing, sandblasting, etc.

 

Q2

Is the component printed with chromium powder biocompatible?
Answer: Chromium has biocompatibility in certain applications and can be used for medical implants. However, its biocompatibility may be affected by the powder composition, purity, and manufacturing process. Therefore, sufficient evaluation and testing are required before use.

 

Q3

What is the corrosion resistance of chromium powder?

Answer: The corrosion resistance of chromium is one of its most prominent characteristics, especially its ability to form a passivation layer in certain media, protecting the substrate from corrosion. This is very important for applications that need to withstand harsh environments.

 

Q4

How does the sphericity of chromium powder affect 3D printing?

Answer: Chromium powder with good sphericity can improve the flowability and packing density during the printing process, reduce the gaps between powders, and thus improve the quality and performance of printed parts.

 

Q5

What 3D printing processes are suitable for chromium powder?

Answer: Chromium powder is suitable for powder bed melting (PBF) processes, such as selective laser melting (SLM) and electron beam melting (EBM). These processes can construct objects layer by layer through selective laser or electron beam melting.
