The Correct Option is C
Solution and Explanation
P: Atomization → Description 2
Atomization is the process used for producing fine metal powders by breaking up a molten metal stream using high-pressure gas or water jets.
Q: Sintering → Description 3
Sintering involves heating metal powders below their melting point so that diffusion occurs and particles bond together to form a solid part.
R: Compaction → Description 1
Compaction presses blended metal powders into a required shape using dies and high pressure, forming a green compact.
S: Infiltration → Description 4
Infiltration involves placing a slug of low-melting-point metal in contact with a porous sintered part and heating, causing the molten metal to fill the pores.
Thus, the correct matching is:
P–2, Q–3, R–1, S–4
