Why is powder metallurgy a green technology?
This success is due to the advantages the process offers over other metal forming technologies such as forging and metal casting, advantages in material utilization, shape complexity, near-net-shape dimensional control, among others. These, in turn, contribute to sustainability, making powder metallurgy a recognized green technology.
How many steps are there in powder metallurgy?
The powder metallurgy (PM) process is more complex than 5,000 years ago. Still, it can be broken down into four steps: 1. Powder Production Metal powder is the raw material of the PM process, produced by grinding, crushing, atomization, or chemical reactions.
What is metal powder used for?
The metal powder is usually iron, and additives include a lubricant wax, carbon, copper, and/or nickel. This produces precise parts, normally very close to the die dimensions, but with 5–15% porosity, and thus sub-wrought steel properties. This method is still used to make around 1 Mt/y of structural components of iron-based alloys.
What is powder metallurgy process?
Eliminates possible waste and guarantees a high production rate. In powder manufacturing, the three main methods are mechanical, chemical, and physical powder manufacturing methods. However, the powder metallurgy process comprises of four necessary steps: powder manufacturing, powder mixing, compression, and sintering.
