pulverimetallurgian

Pulverimetallurgia, also known as powder metallurgy, is a manufacturing process that involves the creation of metal components from metal powders. The process typically begins with the production of fine metal powders, which are then compacted into a desired shape. This compaction is usually achieved using specialized presses and dies. After compaction, the resulting "green compact" is heated in a furnace at a temperature below the melting point of the metal. This heating process, known as sintering, causes the powder particles to bond together, forming a solid and durable component.

The advantages of pulverimetallurgia include the ability to create complex shapes with high precision, often eliminating or reducing the need for subsequent machining operations. It also allows for the production of materials with unique properties that cannot be achieved through conventional melting and casting methods, such as porous materials for filters or parts with controlled porosity for lubrication. Furthermore, powder metallurgy can be an efficient process for producing small parts in large quantities, leading to cost savings. Common applications range from automotive components like gears and bearings to aerospace parts, medical implants, and consumer goods.
