Gas atomization translated to Vietnamese would be "Phân tử hoá khí." is a fascinating and complex process crucial in the production of high-quality metal powders. If you’re diving into the world of metallurgy, 3D printing, or advanced manufacturing, understanding gas atomization is a must. Let’s embark on a journey through this intricate process, exploring its nuances, applications, and more.

Overview of Gas Atomization

Gas atomization is a technique used to create fine metal powders by disintegrating molten metal into droplets using a high-velocity gas stream. This method ensures uniform particle size, shape, and distribution, making it ideal for industries that require precision and consistency.

Key Details of Gas Atomization

• Quy trình: High-velocity gas stream disintegrates molten metal.
• Products: Fine metal powders with uniform size and shape.
• ỨNG DỤNG: Additive manufacturing, metallurgy, powder metallurgy, coatings.

How Gas Atomization Works

Gas atomization begins with melting the metal in a crucible. Once the metal reaches a molten state, it is forced through a nozzle. Here, a high-velocity gas stream (commonly nitrogen, argon, or helium) strikes the molten metal, breaking it into tiny droplets. These droplets solidify as they fall, forming fine metal powders.
