Infiltration:

Filling the pores of sintered product with molten metal to improve the physical properties.

Impregnation:

Filling of Oil, Grease or other Lubricants in a Sintered components such as Porous Heating

Machining:

Removing excess material by using cutting tool to imparts specific features such as Threads, Grooves, Undercuts etc, which are not practicable in powder metallurgy process.
