Powder metallurgy refers to the science of production and working of metals into fine powders, which can further be pressed and moulded to form objects. The process is carried out by heating compacted metal powders below their melting points.

Powder metallurgy for computer science and mechanical engineering is not only important for the GATE exam, but also to prepare for IES (ESE), UPES, BITSAT, ISRO, and other mechanical engineering exams. This article mentions important powder metallurgy topics for GATE ME, powder metallurgy GATE notes, powder metallurgy GATE ME syllabus, and powder metallurgy study material for GATE ME.

Important Powder metallurgy Topics for GATE ME



Powder Production

Powder production is the first step in which raw materials are converted into powder form. Powders can either be pure elements or pre-alloyed powders. Methods involved in powder production include atomisation, reduction, and electrolysis.


Compaction is a process by which the porosity of an element is reduced by mechanical means. The fundamental purpose of compaction is to get a green compact which can ensure further handling operations.


Sintering is done at the most optimal atmosphere to bond atoms. The process of bonding occurs when atoms diffuse.

Secondary operations

Grinding, repressing, plating are considered as secondary operations, and they are performed to ensure great surface finish and corrosion resistance.

Tips to Solve Powder metallurgy for GATE
