Assertion (A): In atomization process of manufacture of metal powder, ...
Assertion and Reason Explanation:
Assertion (A): In the atomization process of manufacturing metal powder, the molten metal is forced through a small orifice and broken up by a stream of compressed air.
Reason (R): The metallic powder obtained by the atomization process is quite resistant to oxidation.
Explanation:
- Atomization Process: In the atomization process, molten metal is forced through a small orifice and broken up into small droplets. These droplets solidify rapidly to form metal powder particles.
- Role of Compressed Air: The compressed air helps in breaking up the molten metal stream into fine droplets. This results in the formation of small and uniform metal powder particles.
- Resistance to Oxidation: The metal powder obtained through atomization process tends to have a high surface area to volume ratio, which makes it more susceptible to oxidation. However, certain metals like stainless steel or aluminum can form a protective oxide layer on their surface, increasing their resistance to oxidation.
- Correct Answer: Option C - A is true but R is false. While the atomization process does involve forcing molten metal through a small orifice with compressed air, the resistance to oxidation of the metal powder obtained depends on the type of metal and not solely on the atomization process.
In conclusion, while the atomization process is essential for producing metal powder, the resistance to oxidation of the powder is determined by the properties of the metal itself rather than the process of atomization.
