Alloy powder manufactured by the following process have spherical shapes ?
Correct answer: C. Atomisation
- A. Electrochemical deposition
- B. Gaseous reduction
- C. Atomisation
- D. Mechanical attrition
Explanation
Atomisation breaks a molten alloy stream into droplets, which solidify into nearly spherical powder particles because surface tension minimizes their surface area. Mechanical attrition, in contrast, usually produces irregular particles.
