Manufacturing Processes of TZM Powder

TZM powder is produced through a combination of powder metallurgy techniques and consolidation methods. These processes ensure the desired properties and characteristics of the final product.

Poederproductie

• This is a common method where molten TZM alloy is sprayed into a cooling gas (often air or nitrogen) to form fine powder particles. The cooling rate and gas velocity influence the particle size and morphology.
• In this process, TZM alloy powders are subjected to intense mechanical deformation, resulting in a homogeneous mixture of elemental powders or pre-alloyed powders. This technique is often used to produce TZM powders with specific compositions or microstructures.
• This method involves injecting TZM powder into a high-temperature plasma stream, where it melts and solidifies rapidly to form particles. Plasma spraying can produce powders with unique properties, such as porosity or surface coatings.

Powder Consolidation

• This process involves applying pressure to TZM powder at elevated temperatures, causing the particles to bond together to form a dense solid. Hot pressing is often used to produce high-density components with precise dimensions.
• TZM powder is heated to a temperature below its melting point, causing the particles to bond through atomic diffusion. Sintering can produce components with various porosities and mechanical properties.
• TZM powder is consolidated into a preform and then shaped through hammering or pressing at elevated temperatures. Forging can produce components with complex shapes and improved mechanical properties.

Oppervlaktebehandelingen

• TZM powder can be coated with other materials, such as refractory metals or ceramics, to enhance its properties, such as oxidation resistance or wear resistance.
• TZM powder can be heat treated to modify its microstructure and improve its mechanical properties, such as strength or ductility.
