POWDER METALLURGY
16 avr 2020 · The powder metallurgy process consists of mixing elemental or alloy powder compacting the mixture in a die and then sintering or heating |
The four basic steps to the powder metallurgy process are powder preparation, mixing and blending, compacting, and sintering.
These steps have been used over the centuries to produce a variety of products.
Why are metal powders blended?
The first step in powder metallurgy is blending.
It is a process wherein the powders of raw metals are being selected and portioned into alloys.
Blending allows the conversion of copper, tin, zinc, iron, and other raw metals into alloys such as bronze, brass, iron copper, and others.
What is blending in metallurgical terms?
Blending of powders is defined as the thorough intermingling of powders of the same nominal composition.
Premixing is the preparation of a uniform mixture of two or more components.
What methods are used to blend powders?
There are several methods which are involved in mixing some of the pharmaceutical powders here we can state convective mixing,shear mixing and Diffusive mixing.
Convective mixing: also known as “Macro-mixing.” Includes moving a collection of particles from one region of a powder bed to another.
