2. Surface Treatments: Coatings and platings can enhance corrosion resistance.
3. Operating Environment: Humidity and exposure to chemicals can accelerate rusting.
4.  

Rust Prevention Strategies in PM Parts:

• Use stainless steel materials for corrosion-prone environments.
• Apply protective coatings (e.g., zinc or nickel plating).
• Utilize heat treatments for additional protection.

Proper material selection and preventive measures ensure PM components maintain their structural integrity in challenging conditions.
