Composition of Plasma Atomisation
Plasma Atomisation involves the use of a plasma torch to melt a metal feedstock, which is then atomized into fine droplets by a high-velocity gas stream. This process ensures a controlled and uniform particle size distribution, resulting in metal powders with superior properties.
The composition of the metal powders produced through Plasma Atomisation can vary significantly depending on the material used. For example, titanium alloys like Ti-6Al-4V are composed of titanium, aluminum, and vanadium, providing a balance of strength, lightness, and corrosion resistance. Stainless steel powders, on the other hand, consist of iron, chromium, and nickel, offering excellent durability and corrosion resistance.
Characteristics of Plasma Atomisation
One of the defining characteristics of Plasma Atomisation is the production of highly spherical particles with a narrow size distribution. This uniformity is crucial for applications requiring precise control over powder behavior, such as additive manufacturing and high-performance coatings. The spherical shape also enhances the flowability and packing density of the powders, making them ideal for various industrial processes.
Additionally, Plasma Atomisation enables the production of metal powders with high purity levels. The process minimizes contamination and oxidation, ensuring that the powders meet stringent quality standards required for critical applications.
