University of Technology Subject: Powder Metallurgy Materials
Powder metallurgy has some serious drawbacks as given below which limit its application in narrow field: 1 It is difficult to secure exceptionally high purity powder with satisfactory quality without which it is impossible to prepare the parts with optimum physical properties Also it is highly expensive to prepare such powders 2 |
What factors affect the selection of materials in powder metallurgy?
PRODUCTION OF METAL POWDERS The selection of materials in powder metallurgy is determined by two factors.i) The alloy required in the finished part. ii) Physical characteristics needed in the powder. Both of these factors are influenced by the process used for making powder.
What is powder metallurgy?
Definition of Powder Metallurgy • Powder metallurgy may defined as, “the art and science of producing metal powders and utilizing them to make serviceable objects.” OR • It may also be defined as “material processing technique used to consolidate particulate matter i.e. powders both metal and/or non- metals.”
How a metallic element can be produced in a powder?
CHEMICAL METHODS • Almost all metallic elements can be produced in the form of powders bysuitable chemical reactions or decomposition. Mostly chemical methods are based on the decomposition of a compound into the elemental form with heating or with the help of some catalyst. In most cases such processes involve at least two reactants.
What are the physical methods of powder production?
Physical methods of powder production:i) Water atomization ii) Gas atomization iii) Special atomization methods The choice of a specific technique for powder production depends on particle size, shape, microstructure and chemistry of powder and also on the cost of the process. 1.
