Description
Powder Metallurgy (P/M) is a metal processing technology that
converts metallic powder into useful engineering components of
various shapes and properties. The major advantage of P/M is
its ability to make highly complex, high precision parts at a
fraction of the cost of competing technologies such as machining
and investment casting. It has gained widespread popularity in
a wide array of applications from automotive seat belt components,
electric contacts, soft magnetic cores, to a variety of structural
applications.
Powder Metallurgy uses sintering process for making various
parts out of metal powder. The metal powder is compacted by placing
in a closed metal cavity (the die) under pressure. This
compacted material is placed in an oven and sintered in a
controlled atmosphere at high temperatures and the metal powders
coalesce and form a solid. A second pressing operation,
repressing, can be done prior to sintering to improve the
compaction and the material properties.
Powdered Metal Materials Properties:
1. Dry working condition, provides maintenance free operation.
2. Can be applied in widely temperature ***0 to ***0
3. Suitable for high static and dynamic load
4. With low and smoothly coefficient of friction and without
stick-slip effects
5. Suitable for dirt, impact and edge load
6. Good thermal conductivity property
7. Suitable for reciprocating, rotating and oscillating
movement with start frequency and difficulty to form oil film
occasions
8. With lower wear rate and long life service
Advantages of Powder Metallurgy:
1. Various material selection and energy saving
2. Minimum secondary machining process
3. Cost saving for complicated shaped product
4. Meting any dimensional product requirements
5. Improving dimensional precision
6. Achieving required microstructure with various material
selection
7. Supreme surface treatment
8. Improving hardness and endurance
by adequate heat treatment process
9. Manufacturing uniform products
*0. Suitable for self-lubricants & filters for minute
porosity
*1. Good for mass production
