- Metal Powders are
precisely engineered materials that meet a wide range of performance
requirements. These engineered materials offer wide latitude to develop
materials with properties tailored to the application through metal
alloying. These engineering properties are affected by several factors
that include material type, powder fabrication process and the component
manufacturing process
- Powder metallurgy
is a highly developed method of manufacturing reliable ferrous and
non-ferrous metal parts. The process entails mixing powders and
compacting in a die to give shapes that are then sintered or heated to
bond particles metallurgically. As more than 97% of the starting
materials reach the finished product, powder metallurgy is a process
that conserves both energy and materials.
- Metal powder technology
is one of the most established production methods nowadays in all kinds
of industries
- Metals commonly used in
powder form include iron, steel tin, nickel, copper, aluminum and
titanium. Refractory metals include tungsten, molybdenum and tantalum.
Bronze, brass, stainless steel and nickel cobalt alloys are also used.
- Powder particles range
from 0.1 to 1000 micron in size and must be carefully controlled. Major
production methods include the atomization of molten metals, reduction
of oxides, electrolysis and chemical reduction. Particle size
distribution is a critical parameter. Powders with narrow particle size
distributions behave predictably during mixing and mould filling;
perform better during hot or cold compaction and sintering; will give a
uniform coating in spray applications; and ultimately will give improved
final product quality.
- Metal powders are made
either by gas atomization , or grinding , and are then classified using
dynamic classifiers or cyclones to obtain the precise particle size
distribution. To form the final end-user product, the metal powders are
then used in various consolidation processes such as extrusion,
injection molding, blending, compaction, sintering.
- The metal powders are
characterized by their morphology, which can be described as irregular,
blocky or spherical, and powder size. Physical properties such as
hardness and ductility, chemical properties such as reactivity and
impurities, and bulk properties such as flow properties, apparent
density, tap density, compressibility, and green strength are among the
properties by which the metal powders are characterized. High quality
fine metal powders that are free of refractory and oxide contaminants
with a narrow particle size distribution are used for the production of
plasma spray coating targets as well as for the production of structural
and functional materials.
- Inert gas atomization,
combined with melting under vacuum or under protective atmosphere
therefore is the leading powder-making process for the production of
high-grade metal powders which have to meet specific quality criteria
such as spherical shape, high cleanliness, rapid solidification,
homogeneous microstructure.
- Metal powders are used
in a wide variety of applications which include dietary supplements in
food processing, additives in paint and other coatings, as pigments in
printing and packaging, in solid fuels and cements. Probably the major
area though is in the cost-effective production of metal components for
a vast array of end uses.
- Production of
high-quality metal powders is becoming important to meet the increasing
demand for manufacturing advanced materials. A number of standard powder
production techniques have been developed to meet the increasing demand
for high-purity metal powders.
- Iron powder
companies have introduced new powders for high-performance applications
and aiming R&D at lower-cost alloying elements, bonding technology
and high-density processes. A vacuum annealed tool steel powder was
commercialized last year that allows routine compacting and sintering
without adding graphite. Copper powder makers have developed materials
for new applications such as metal injection molding, frangible bullets,
heat management and welding electrodes.
- Metal powder makers are
developing new high-density steels and processes to achieve a density of
7.5 grams per cubic centimeter by single pressing and sintering.
Achieving densities of 7.5 and above will certainly open up new markets,
with PM gears and sprockets for automotive transmissions being but two
such potential applications. Nonferrous powder producers are also
developing new materials such as super high-strength bronze alloys for
PM gears. Some other new applications for copper-base powder s include
cold spraying, lead-free brazing alloys and special materials for
frangible bullets.
- Industry trends
indicate the need for economical fine powder grades for a growing number
of applications.
- Particle size, shape
and percentage yields are the important characteristics associated with
the manufacture of suitable powders.
- Advancements in high
pressure water atomization
technology can now produce fine powders with unique physical
characteristics.
- Fine particle size
distributions with shape modification, without requiring additional
mechanical or thermal secondary operations, provide suitable
alternatives to more costly inert gas atomization processes.
- In centrifugal
atomization for metal powder production, the key to the control of the
particle sizes is the design of the atomizer
- A cup atomizer with a
slope angle of 60– 70 would result in small spray droplets and thus a
fine powder.
