Powder Metallurgy Quiz

Powder Metallurgy Process

• The main steps in the powder metallurgy process are: production of metal powders, blending, compaction, and sintering.

Atomizing Process

• The atomising process is used to produce metal powders in powder metallurgy.
• It is used to break down molten metal into small particles.
• The primary purpose of the atomising process is to create metal powders with a desired size and shape.

Powder Metallurgy for Specific Metals

• The primary reason for using powder metallurgy for certain metals like Tungsten is that they have high melting points and are difficult to process using traditional methods.
• Powder metallurgy allows for the production of parts with unique properties that cannot be achieved through traditional methods.

Ball Mills

• The role of ball mills in powder metallurgy is to further process the metal powders produced through atomising.
• Ball mills are used to crush and grind the metal powders into a finer size and shape.

Sintering

• Sintering achieves the consolidation of metal powders into a solid part in the powder metallurgy process.
• The main purpose of sintering is to bond the metal powder particles together to form a solid part with desired properties.

Factors Affecting Particle Size

• The factors that affect the size of particles produced in the atomising process include the flow rate of the molten metal, the gas pressure, and the distance between the nozzle and the powder collection system.
