Development and Optimization of Industrial Lubricants for Powder Metallurgy

Powder Metallurgy (PM) is a production method suitable for accurately fabricating complex shapes to a desired size and shape, thus minimizing the need for machining. This makes it cost effective in comparison to other manufacturing technologies.
In order to facilitate the production of PM parts, a lubricant is added to the iron based powder during mixing. The lubricant affects the internal friction between the particles during compaction as well as reduces the total energy needed to eject the part from the die after compaction. However, using lubricants decreases the density of the final product. In addition, the powder mixture after mixing with the lubricant must have fast flow and uniform die cavity filling consistency so that low rejection rates and good part integrity can be attained.
There are different physical factors which effect powder properties. TO BE CONT’D
