pölymetallurgiaa
Pölymetallurgiaa is the Finnish term for powder metallurgy. It is a metal forming manufacturing process where a metal powder is compacted into a desired shape and then sintered. Sintering is a heat treatment process that occurs below the melting point of the metal, where particles bond together to form a solid mass. This process allows for the creation of complex shapes and parts with specific material properties.
The powder metallurgy process typically begins with the production of metal powders. These powders can be made
Following compaction, the green part undergoes sintering in a furnace. During sintering, diffusion processes occur at
Powder metallurgy is advantageous for producing parts with high precision and complex geometries that are difficult
